One of our fabulous Facebook friends found this movie on YouTube. It's a great way to use the Clip it Up Mini and Upper Tier to store Cricut Cartridges. The Mini and the Upper Tier are the same height and can hold items up to 8".
If you don't have desk space then check out one of our wall units : Swinging Wall Arm, Wall Mount, and Under the Shelf Rod. These are other great ways to store your Cricut cartridges.
