ELFENSTALL 10pcs 3ml Roll on Glass Bottle for Essential Oil - Empty Aromatherapy Perfume Bottles - Refillable Slim with Metal Ball and Black Lid Amber + Free Pipette Dropper Clean Cloth

I like the size, the packaging is very nice too - a great way to keep them before you want to use them.However -- out of the 10 I have used 6 so far and three of the roller balls have fallen out! Not good - a waste of my essential oils.OK so I can "deal" with it being careful every time I use them to be prepared - BUT --- I like to give rollers of oils and blendsto friends - the thought of that happening to them is not good, making me not gift out as much as I would like.If it was just one I'd say oh well something is bound to happen, but three out of 10 (and I've only used 6 so far) is not a good record.

Great, just what I needed. Only thing, bottom cracked on one of them. Lesson learned, I don't put me thumb on bottom anymore.

Roller balls started to fall out after a few months of continued use.

I use these roller bottles to give out samples of essential oils two people and they work great! I rarely have any problems with leaking and the cats it's pretty good against the glass.

I will use them for my essential oils.

I really love these bottles so far.

These are great for making individual sizes of your oils.....10pcs. is great. I will buy these again....good price which is important for me living on a set budget.

Perfect for my essential oil mixes! Love the small size- good sample size to give out to friends and family!
