They fit nicely on my 15ml young living essential oil bottles but i keep them stored in the cabinet as i worry that tossing them in my purse would break down the rubber at the top and leak into the eo thus destroying the integrity of the product

Other than this problem they are perfect but because of this i am only giving them four stars

The components of each blend need to be written down and changed as needed so it can be reproduced

Just a big shame they have these odd shapes dropper ends

The bottles are leak proof however the rubber under the dropper starts to tear away after a while
