Our Wooden Stackable Storage Bin can be used as a merchandiser as a beautiful shelf display, the closet or the kids’ room. It is a great way to keep things like toys and shoes neat and organized. The outside dimensions are 20 x 12 x 11 1/2″. When you stack them 3 high, they have a height of 34 1/2″. These bins do not interlock. If you are going to stack them up, they should be secured to the wall with screws to avoid tipping. We can stain, laser engrave or full color digitally print your message on the bins, for an additional fee per image.
