Beware, it does NOT hold 30 ml bottles.
It's ok, but it's my fault that I did not read the description carefully enough. I needed a carrier for mu essential oils that held 30 ml bottles as well. My only complaint and not about the product. Actually it is very good at what it does, but I am unable to use all of the compartments. I have lots of 30 ml bottles.
