My daughter loves essential oils.  She is always mixing different oils for different ailments or aches. I purchased the 6-pack of deep cobalt blue glass roll-on bottles for her to put some of her mixtures in.

I like these bottles, as the deep cobalt blue coloring protects the essential oils from UV rays that can damage the oils. They have stainless steel roller balls, which are necessary with oils, as oils will break down plastic rollers. The lids fit snuggly, preventing any leakage, even when rolling around in my purse.

The set included a 3ml dropper for adding the oils to the bottles without spilling it, and included a set of stickers, so that the bottles could be labeled.

Snap in the roller-ball by gently placing the roller-ball in the bottle and then firmly tighten the cap until the roller-ball snaps in. Remove the roller-ball by applying pressure with the cap.  Easy peasy.
