Already have one of our easels, storage carts or a few tubs in your class that could use a lid? Adding a see-through hinged lid to your Copernicus product makes it easy to keep things tidy and allows the tubs to be stacked. The hinge eliminates the need to remove the lid when accessing materials inside, so no missing lids! TUBS NOT INCLUDED! This lid fits on ALL of our Large Open Tubs, Large Divided Tubs and Stubby Tubby.
