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 from 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 90lbs! Great for maker space storage! Also comes with a pegboard kit - a great accessory to add even more function to your book browser cart! Attach the board and pegs and start sorting and organizing your favorite items.
