This is a great storage box for craft items, fingernail polish, hot-wheels and even essential oils. I really like how it is 2 sided with latches for both sides.
The plastic box is 13 1/2 inches wide and 13 inches tall including the handle. It is 3 inches thick. Both sides are exactly alike having 21 (1 5/8" x 3 3/4") size sections and 5 other sections that can be resized as needed, giving you 26 sections on each side for a total 52 sections.
I have found the organizer very useful for storing and traveling with items. The sections help keep my nail polish organized and easy to find. The box is also great to store my grandkids hot-wheels in especially since it is see-through and easy to spot which one they want quickly.
