Great little roller!
We bought these little roller bottles to make small first aid kits for summer. Honestly,  my expectations were pretty low,  after having poor success with other bottles (different sizes and styles from other companies). But I've been pleasantly surprised.  They let just the right amount of oils out, without leaking!  They work so well,  that I am comfortable letting my child use them, and I'm placing another order for them this week!
