I Use it for pain gel. Rolls great and really like the easy fill. Cap screws off, then you screw off the roller part and fill. Remember to remove the little round insert under the roller ball section.HIGHLY RECOMMEND THIS PRODUCT

Helped me save money. Great for holding the body oils I use for cupping.

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.

I got these containers to apply lotion and muscle rub. I love how easy it is to use. I use less products due to the roller applicator. I am very happy with them.

My first review es to quick.after a few days The roller leaked like a faucit.

These refillable roll-on bottles are genius! I use them for pain relief rubs that I buy in tubes and transfer to these. No more oog on my hands. I thin the ointment with a little distilled water if it's a bit thick. Works perfectly.

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.

I don’t write many reviews but these are so terrible I felt obligated too. These bottles are absolute junk. They leak like a sieve. One bottle won’t even screw together. I will be retuning these promptly.

I use this for the fasciablaster oil. I can buy the large bottle and fill my own roller bottles so I don't use too much oil and make a unholy mess in my bathroom. They work well, I bought some for my friend as well.

Good size, decent material fast shipping

Love them!

Used to send sunscreen to school with my kids. So far not leaking and dispensers sunscreen well.You do need to press down firmly as you are screwing the top on to get it to engage
