Not Air Tight!  Lost Product!!!
Totally adorable bottles and there is just a trick to put them together but it was easy.  I am so disappointed!  I was using these for part of gifts for a brunch.  I put Sacred Frankincense in them and within 2 weeks the oil evaporated out of most of the bottles!  Don't put anything in them that you want to last.  This was a VERY costly lesson!
