I have a few different boxes for storing all of my essential oils in but this is my favorite hands down. I just love the beauty of this box. It is a 3 tiered box. The top section opens to 2 tiers. The top tier holds 15 bottles up to 15ml, the 2nd tier holds 25 bottles up to 15ml. There is a drawer that opens from the front and it will hold up to 16 of the roller bottles. There are dividers in each tier and the dividers can be removed. The box is natural wood so you can paint it, stain it, or personalize it any way you want it. This really is a very beautiful box. The box measures 9 inches wide by 9 inches thick by 10 inches tall.
