This is the perfect size to fit two on our shelf. They have ample room for the activity. I hope they offer more colors in the near future. The depth keeps items from falling to the floor, while the lip is just right for a handle to lift and carry with grace.
My hobby works with very tiny delica beads. I needed a tray with sides that aren't too deep. I place a piece of vellux in the bottom and the beads stay in place while I work over the tray. I bought four trays and use the others for work in progress that I can put aside for a while.
These trays are such a nice size. They are light and easy for toddlers to carry. The lip on the tray makes a nice addition when it holds a pouring work.
