A Must Have if You Make Essential Oils
I've known about essential oils for my dogs and recently decided to try them for myself when a friend made a set for me.  She used these bottles and I love them, so I ordered a set for myself along with a book on making essential oils.<br /><br />The roller is smooth and works well.  There's no leakage, which is great since oils can stain clothing.  And my room doesn't smell strongly of the oils I'm using, so the seal on the bottle is secure.<br /><br />I'm very excited about the quality.
