INOVART Paint and Ink Mixing Trays 6" x 9" x 1/2", 10 per Package

It's a styrofoam tray. Not sure what else you need to know. Unlike another reviewer, I did not think these were flimsy. It's just a standard styrofoam tray. Exactly like meat comes in at the supermarket.

These 10 trays are made from a very weak kind of styrofoam. They crack and break way too easily.

I thought it came with more. Very disappointing.

I used them for Halloween to display various organs. Surprisingly sturdy.

Ok

You can totally pick these up at S&F like 100 for under 9 dollars. I guess they put ART in the name and the price jumps. I was using these to store bait for salmon fishing.
