10ML(1/3oz) Glass Roller Bottles with Stainless Steel Ball and Blue Metal Cap

I had gotten some 2ml bottles when I first started with essential oils, unsure if I would like using EOs in rollerballs. Well it turns out I do, and it also turns out that for a variety of reasons 2ml is not the only size you want to have if you do have them (I still use them, but now I know better how). But this is a review of the 10ml size, which is perfect for many recipes you’ll find online or create yourself. These bottle are made of a thick, sturdy-feeling cobalt blue glass which can be washed and reused when empty. The roller balls I received were all stainless steel, as they are meant to be. They roll pretty easily, though I like to me sure of this by rolling them a bit before popping the rollerball mechanism onto the bottle. Maybe “popping” isn’t the right word exactly - I find to get the rollerballs on its more of a very firm push I use with the heel of my hand. This is good actually because a tight fit/seal means no leaks. If the assembly were to go on too easily, it would mean it would be easy for oil to leak around the seal. As it is I have noticed some minor leaking with one bottle, but storing them upright has so far prevented that from being much of a problem (I will be traveling with them for the first time at the end of this week, and plan to carry them in a plastic sandwich bag to prevent accidents). One thing that is good to know - only fill the rollerball up to about the shoulders or maybe a bit further. If you try to fill the neck, the rollerball won’t be able to sit flush on the bottle when you push it in, no matter how much you push it down - and a flush, firm seal is really important to prevent leakage. I have made several of these and use them a lot for many different uses. If you buy these, you shouldn’t be disappointed!

I use these bottles all the time for my Young Living Essential Oils roller bottle recipes. These bottles are good quality. They hold up in the long run for use over and over again. Being the color blue, they protect the oils from sunlight so the oils don't lose their efficiency as quickly. The metal roller balls are fabulous. They roll smoothly without getting "stuck" and they seal securely with the bottle mouth so there is no leakage. And on top of all of this, they are pretty too - so I carry them in my purse all the time. I have ordered these several times and have never been disappointed!

worked well for what I needed. great shipping

These are the best. Color coded tops make it easy to remember which fragrance is which. They roll on nicely and don't leak. I will definitely reorder these.
