This sturdy cart is designed to provide plenty of storage with 23 tubs for maker materials, robotics and manipulatives. The different colored tubs aid color coding and all the tubs can be removed form the cart. The removable, dry erase board is perfect for collaboration and sketching out ideas. The frame is designed with strong 1" tubing and includes large 5" casters that move easily over almost any surface and stand up to the rigors of being maneuvered throughout a school. This cart can hold up to 90 lbs.
