The Roller Ball Heads don't work.

Normally I don't write reviews. In this case, am just sending out a warning to buyers. These lovely vials arrived and I shared them in a few events. Used about 12 vials. 3 people who received my blends later told me that their Roller Bottles that i had given leaked way too much oil and they couldn't use them. It's almost like the ball is too small for the plastic holder? or the plastic expands and then loads of oil comes out when one tries to use them. I can't return my pack of 24, so guess I will try to buy some replacement roller ball parts from a different company. I don't think I will be ordering from this company again.
