Taiyin 12 Pcs Plastic Flat Storage Tray Classroom Turn in Tray Paper Bins Teacher Classroom Containers Paper Organizer Tray School Office Letter Basket Art Book Organization File Holder (Bright Color)

These trays are marketed as classroom trays but are not limited to classrooms only. I got them to store my craft supplies and sort the orders.The different color bins are useful for marking them properly and I believe would be useful in classrooms too when teachers have to tell kids about a specific tray. For me, it is useful to just remind me which order goes in which tray.The trays do have good strength, I tried putting around 2 pounds of supplies in them and they do not wobble when I carry them. The plastic is not too thick but the structure of the tray lets it hold much weight.The size of these trays is quite large and can easily store A4 size paper. With slightly over 3 inch height it can hold a lot of supplies. Just to note, the dimensions mentioned in the product dimensions are not the size of individual trays, but the size mentioned is about this item section has the most accurate outer dimensions the inner useful volume is slightly less than it.Overall it is a good and recommended product.

Product is super cute, vibrate colors. Very thick & sturdy plastic. Only complaint is that a standard piece of paper does not lay flat. Definitely long enough for paper, but just barely too short wide wise that paper won’t lay flat. Needs to be about 1/2 wider.
