I have a LOT of oils and have been watching for years for a cabinet that would hold them all. This is wonderful! I did fill EVERY 15 ml and roller spot and have only a few 5 ml empty. There are a few changes I might suggest. There are plastic glides on the sides that turn out. Those come off easily and we've attempted to put them back on with another adhesive hoping they will stay. Be forewarned to gently lift as you turn out each side to hopefully keep the glides attached. Also, I, like others, would have LOVED this to have been in white. (Granted, I certainly won't be able to justify another large amount of $ if it does come in white at some point, but another oiler would be happy!).
