These clear roll-ons are great for my blends. The tool makes it easy to open and close.

These bottles were exactly what I was wanting.

These roller bottles are very pretty and modern looking, very in-line with the roller bottles I see on Instagram. You could easily add cute vinyl labels onto these bottles. They function as expected, easy to open (even come with a little top-remover tool), screw on well/straight and roll smoothly. They release the fluid smoothly and evenly. The only reason I docked a star was that they were packaged horizontally, stacked in the box, rather than standing up straight. This always worries me for potential breakage or damage. The metal caps are also a little thin (plastic underneath), so they may ding up or scratch with use.

This set of 12 arrived neatly packaged and in perfect condition. I ordered the gold set which included 12 bottles with roller balls, lids, and opener. Everything works as intended and will make amazing EO blends.
