I ordered these to use with some arnica oil for my shoulder I had so my hands didn't get so greasy. I've only used one of them so far, but it works great, the roller ball rolls easily and dispenses the oil evenly. Absolutely no leakage. I think the bottles are great quality for the price.

I got these to make it easier to apply my essential oils to my body after my shower. Absolutely, mind-blowingly genius! My arthritis no longer keeps me from using my oils! Easy to open, refill, close, hold, and use! I'm never going to use those 30ml roller bottles all over my body again - too hard and takes too long! These speed up the whole process!

I use these refillable roll-on bottles for containing and applying a transdermal DMSO-base NSAID solution that I make. They hold a good amount and the large tolerance around the nylon rollerball allows the liquid to flow out and roll on very easily. My only concern is that I have struggled with occasional unintended leakage at the connection between the main container and the roller-ball assembly. There are only a couple of thin plastic threads holding these two parts together, and this joint is independent of the cap/cover threads. I have experienced leakage in two situations: (1) if I even gently shake the liquid (with or without the main cap on), and (2) if I unscrew the main cap and invert the roller assembly, several drops often leak down on the floor, countertop, or somewhere unintended on my skin. The way I have countered this tendency to leak is always to separately tighten the roller-ball assembly to the bottle, both when removing and removing the main cap. I also am becoming less cautious about-overtightening the connections. Despite the #2 plastic walls of the bottle seeming to be rather thin, and the small number of threads holding the rollerball assembly to the main container, I have not experienced tears or cross-threading of the components. I also have NOT and do not believe I ever will, subject these containers to the ultimate travel-test: throwing them in my suitcase without first enclosing them in a ziplock or other more leakproof container.

These are exactly what I’ve been looking for for well over ten years! I’ve been using an old deodorant bottle with a roller ball to apply baby oil after a hot shower. Had to pop out the roller ball so as to fill it with baby oil. But now, these are extremely easier to refill since the head unscrews. Take the roller ball head off, refill, screw the head back on. This most definitely fits KISS - keep it simple stupid! If only they were available ten years ago. You can use these with whatever you want to fill them with but they make it so much easier to apply baby oil after a shower - not to much, not to little, just right! Strongly recommend these to everyone!

Kinda thin but works for what you need.

Love these for roll on pain oil I make.

These are complete garbage, yes I know the price is inexpensive but that’s no reason for them to be totally crap.First of all the ball section does not screw on properly and then if you screw it on a little too tight the ball won’t roll….correction, the ball won’t roll no matter how it’s screwed on. All in all, spend a few dollars more and get one that really works.

In our continual quest to free ourselves from the non-stop attacks against our bodies via the pharmaceutical industry and sadly, the horrible commercially-made, processed-food industry, this was just one more step in the right direction. We now use only our own natural deodorant concoctions for everyone in our family, which work great and now that we use these roll-on bottles, they apply just as easily as store-bought roll-ons but without the inclusion of microscopic, toxic metals going into our skin, underlying glands, etc. We couldn't be happier with the ease of use in both application and when refilling. Highly recommended.
