20 Pack Set 2ML(5/8 Dram) Micro Mini Cobalt Blue Glass Roll-on Glass Bottles with Metal Roller Balls - Refillable Slim Sample Vial Aromatherapy Essential Oil Roll On (Blue)

Blue glass is preferred, not as available .. .Handy size for purse or pack, no leaks.

Nice bottles, love the little rollers. They don't roll really well though. But they are super cute.

These are really nice, cute bottles with roller balls. Great for travel. The bottles came with the roller balls already inserted. With the hundreds of roll-ons I have purchased, I had never experienced this. This, to me, is a huge disadvantage. Not only is it a pain to remove all those roller balls (even with the included tool), but also some of the roller balls loose the tight seal so when you try to reinsert the roller ball, the seal is loose and the roll-on leaks. All the supplier needs to do is to not insert the roller balls.

I’ve gotten a bunch of perfume samples in the thin, tall vials, which are difficult to open and use. I bought these and transferred the perfume samples, and they work perfectly. With the included tool, removing the roller ball and filling the vial is super easy. No leaks so far, and the roller balls glide easily. If I need more sample bottles in the future, I’ll definitely order these again.

Love these for keeping sample-sized rollers in my bag and not carrying full-size rollers everywhere.
