Vivaplex, 6, Cobalt Blue, 10 ml Glass Roll-on Bottles with Stainless Steel Roller Balls - .5 ml Dropper Included

I bought these to roll Teatree oil on cuts and essential oils on as perfume. They leak if stored horizontally and they let out so much oil through the rollerball I can’t use them. I haven’t tried them with something thicker like jojoba or olive oil because I did not want these oil’s mixed with a carrier oil. I do not recommend these for any pure essential oil, Teatree oil, cologne, or perfume.

The glass is very good quality and the stoppers are snug and secure. I am not happy with the roller balls though. I have had the balls fall out of a couple of them and an inevitable mess ensued each time. They also seem to be loose and oil drips out when I invert the bottle to utilize the roller. I will not be purchasing these ever again.

They work great, they hold a lot; wish they made one half the size.

as described

Very easy to use, I appreciate the fact that it comes with a syringe.

Very happy with the rollers. I have had no problems with any kind of leaking.

Package arrived as advertised, put it to work right away; it works great
