A palette is bought on two numbers before anything else: how many wells it has, and how thick the plastic is. Everything else โ the outline, the colour, the finger hole โ is a decision about who will use it.
This guide is for the buyer assembling a plastic palette line: school suppliers, art-material distributors and studio retailers. It covers the well layouts that exist in a real range, what wall thickness does to the life of the product, the small design details that decide which account each format suits, and what to fix on paper before a quotation is worth reading.
The well layout is the specification
Ask for a plastic paint palette and you will get a price for something. Ask for sixteen wells, a 6.5 by 10.8 inch body and a thick PP grade and you will get a price for your thing.
Well count and well shape are the two halves of that. Together they set how many colours a student can hold at once, whether paint stays where it was put, and whether the item is a mixing surface or a carrying tray. The plastic palette range is built around the formats below, and that list is how a quotation should be lined up.
| Format in the range | Wells and trays | Listed size |
|---|---|---|
| 12 holes plastic square painting palette | 12 wells, square outline | 4.5 ร 5.1 in |
| Plastic painting palette, round with square paint trays | 4 square trays plus 5 round trays | โ |
| Kids painting palette | 16 wells | 6.5 ร 10.8 in |
| 4-in-1 kids easy painting palette | 10 wells, multi-tool body | 8.9 ร 6.5 in |
| Flower shape plastic painting palette | 7 wells, flower outline | 6.3 in diameter |
| Big round holes palette | 6 round holes, enlarged | 13.1 ร 8.7 in |
| Big round holes palette X | 6 round holes, enlarged | 6.5 ร 4.3 in |
| Base type tray PP materials palette | 7 trays plus a mixing area | 6.8 ร 5.6 in |
| Classic palette with two ears | 6 wells, two lift ears | 6.7 ร 3.75 in |
| Oval flat shape palette, for oil | flat surface, no wells | 11 ร 8.45 in |
| Biggest painting palette square | large square body | 13.4 ร 9.25 in |
Read the first row against the third. Both are square plastic palettes. One holds twelve wells in a 4.5 inch body; the other holds sixteen in a body more than twice as long. A buyer who specifies a twelve-well palette without the size has specified a shape, not a product.
Two details in that table matter more than the rest, and both are easy to miss when comparing quotations. The first is enlarged holes. In the big round holes formats the six round wells are made larger than the classic version so they hold more paint โ the difference between a palette you reload every few minutes and one that carries a working session. The second is the mixing area. Wells alone make a carrying tray; the base type tray adds a flat mixing area beside its seven trays, which is what turns it into a working surface for a studio rather than a paint holder for a classroom.
For a school the arithmetic is simple: more wells in a smaller body is more students served per unit of shelf space. For a studio, fewer and larger wells plus a mixing area is the version that actually gets used.
Wall thickness decides how long the palette lasts
Every plastic palette in the range is PP. The PP is not the variable. The thickness is.
A thin PP body flexes in the hand and takes a set if it is stored under weight. A quality thick PP palette โ the 12 by 8 inch format in the range is built that way โ resists bending and survives being dropped. That difference does not show up in a photograph, and it does not show up in a quotation that lists dimensions only.
It shows up three months later, in one of three ways: palettes that have taken on a curve so paint runs to one side; corners that crack after a term in a classroom tray; and a reorder that no longer matches the first delivery because the thickness was never written down.
So put the grade in the specification, not just the size. Write thin or thick as a line item, keep the approved sample, and compare the next delivery against it โ the same discipline as any other tool in the range.
Small design details decide which buyer the format suits
Three details separate the formats, and each answers a different buyer.
A finger hole. The base type tray PP palette carries a finger hole for grasping, so it can be held in one hand while the other works. That is the format for someone painting at an easel with nowhere to put the palette down.
Two ears. The classic plastic palettes with two ears take their name from raised tabs on the body. They do the same job in a flatter outline, which is what a buyer wants when the palette has to sit in a school tray or stack inside a carton.
A box body. The palette box design stores watercolour blocks inside the palette itself. It is not the cheapest format per unit and it is not meant to be โ it is the one a parent buys once, because the blocks travel with the palette.
Then the multi-tool formats. The 3-in-1 and 4-in-1 kids palettes combine wells with the rest of the paint kit in one moulded body. These suit retail and gift channels far better than a plain sheet, and they suit classrooms less well, because a teacher ordering thirty palettes does not want thirty extra tools to account for.
The same tray serves palette painting in three media, so the search terms split accordingly. A watercolor palette and an acrylic painting palette are usually the same moulded body; acrylic palette paint and palette paint are used interchangeably by buyers describing the paint rather than the tray; and plastic paint palette kids covers the smaller formats. What changes between them is the well depth a buyer wants, not the material.
If you are replacing rather than buying for the first time, the phrasing shifts again. Artist palette, empty plastic watercolor paint palette and paint palette tray all describe the same object from three directions โ the user, the condition and the shape. Misspellings travel too: a share of the demand arrives as paintting palette, and a listing that ignores it loses the click. One more term worth separating: disposable paint palette means the paper sheets, which are a different line with their own specification.
The specification sheet to send a supplier
Four lines are the minimum for a plastic palette: well count, well type, listed size, and material grade. Add two more if the account will run for years.
| Line | What to write | Why it matters |
|---|---|---|
| Wells | count and shape: round, square, or a mix | sets colours held and the price band |
| Well type | classic or enlarged | enlarged holes carry a working session |
| Size | outline dimensions in inches or cm | separates same-count formats |
| Material | PP, thin or thick grade | decides warp, cracking and reorder accuracy |
| Extras | finger hole, ears, box body, colour | matches the format to the buyer |
| Pack | pieces per pack and per carton | sets the reorder multiple |
What goes wrong after the container lands
Palettes that arrive curved. Thin PP takes a set in transit, especially when a carton is packed tight and stacked. A thick grade resists it. If the account is a school, specify the thick grade and pay once rather than replace the order.
Corners that crack. A thin body with a square corner is the weakest point of the product. Enlarged wells and rounded outlines survive classroom use better.
A second delivery that does not match the first. This is the complaint that costs the most, and it nearly always has the same root cause: the order was placed on a size rather than a grade. Write the grade down.
Staining blamed on the material. Acrylic left to dry will mark any polymer. The fix is a smooth surface that wipes clean plus a cleaning routine, not a different material โ which is why our base type and thick PP formats are finished smooth.
Pack size is a buying decision, not a shipping detail
The range includes a twelve-piece pack of square palettes and separate kid-focused formats, and the difference between them matters more than the look.
A twelve-piece pack suits a supplier selling into classrooms, because pack size sets how many students one unit covers and what the reorder multiple is. A multi-tool kids format suits retail, where the pack is smaller and the artwork on the body does the selling. If you list both from one supplier you keep a single specification sheet, a single grade and a single quality conversation โ which is most of the cost of a tooling line.
A plastic paint palette bulk order and a plastic paint palette set wholesale enquiry are not the same request, even from the same buyer: the first is about pieces per carton, the second about what else travels with the tray. Answer both with the same specification sheet, and be specific enough that a paint palette tray 12 holes and its sixteen-well sibling never end up under one title.
Then ask the two questions a catalogue cannot answer: which grade do you hold in stock, and what is the lead time on a repeat order to the same specification.
