Constructive Playthings Messy Trays, Set of 4 Hard Plastic Trays, Multi-Color | Classroom Supplies, Toddler Toys for Creative Play, Set of 4 Trays, Ages 3 Years and Older

Great size trays for so many activities! Can be used for messy art like PlayDoh, paint, shaving cream, to hold beads and other crafts with many pieces.Great for STEM projects!!They also go along w Montessori idea of keeping all your things in one place.

I ordered these for my son, and love them! They are great for crafts, play doh and most of all, kinetic sand. They keep most of the mess in, are sturdy and the colors are nice too. I have even used them outside, for carrying things. The size is great, they are deep enough to play and hold things in, and very sturdy. These are a great buy, in my opinion. They have been a very useful and versatile addition to playtime with my son.

Works great for the things we’ve been using them for. I use them for water play at the dining room table, for containing kinetic sand, for keeping things from rolling away, for a base for our seed station, we even use the red and green trays to signify things at our charging station that need to charge/are charging(red) and the things that are done charging(green). Lots of uses, and I want a second set now.

I have 8 of these trays for use while building my jigsaw puzzles. They are great. I stack them when full of pieces and it works great. One caveat, if you lay out pieces in the trays by shape, you will need to add a foam sheet (mine I got from Hobby Lobby) to keep the pieces from sliding around when you move the tray. I'm sure Amazon has similar foam sheets

I like everything about these small trays except they are not flat. The center area is higher than the edges I suppose so sand or whatever can go to the sides. That is my only complaint - they meet all other criteria perfectly and we are using them everyday. I just wish they were perfectly flat.
