Review on 🎨 ECR4Kids Colorful Plastic Art Trays for Kids: Organize, Create and Explore with Versatile Activity Trays - Perfect for Paint, Beads, Slime, and Sensory Fun! (6-Piece Set) by Carla Anderson

Ideal for picture filing, ideal for 8.5 x 11 sheets. Washable with warm water and mild soap. The structured surface prevents the paper from slipping slightly in the tray. The only downside is that they are a little flimsy and brittle. So if you drop them or hit one of them, the plastic will crack and flake off. We've already managed to knock out a piece of plastic on side 2. The cracks are only about 1/2" x 2" and do not affect its usability, any sharp points may need a light file. The crack/fracture may disappear. We'll definitely get more of this, with kids they'll find a way to break everything if they have enough time.
