This Shelf Storage Unit comes with the three shelf unit (which you will need to cut two of), the center shelf unit that contains 2 compartments, and the organizer base that holds the three boxes neatly together. The file is compatible with both the 8x12 and 12x12 mats and can be made larger if using the Cameo (12x12). Each box is approximately 5-3/4" x 1-1/2" x 2-3/4".
I am storing ink daubers, replacement blades, and twine on the left side, twine on the right, and then I have Stickles Tape the center storage bins.

This box assembles similarly to the following:
