Cositina 8 Pack 100ml/3.38oz Plastic Roller Bottles Empty Refillable Roll On Bottle Leak-Proof Deodorant Containers Anti-perspirant Dispenser for Essential Oil Perfumes Balms - White

Now I can actually reach my lower backbone area! These are terrific, screw-on roller ball top screws on firmly, no leaks. Perfect!!!

Using for magnesium oil. Better than spray!

I used these bottles to dispense a topical pain lotion that works great, but due to the strong smell (mint, etc.) and not being for ingestion I didn't want to get on my hands. These bottles worked as dispensers, but the lotion is a bit watery so it is able to drip past the ball if the bottle is inverted more than a second or two at a time. These do work, so I don't have to wear gloves to use the lotion anymore. They would be great if what your dispensing has a thicker consistency. I would recommend these bottles.

Way better than rubbing on with your hands. The roller actually massages as you apply you lotion.

Does what it is supposed to

I purchased these not for resale of my own product, but to provide an alternative application method for my topical medications. I suffer with chronic pain and sensory processing disorder (amongst other things). I apply topicals all day, everyday to help manage my pain, but I hate having to wash my hands after each application. I started wearing nitrile gloves to apply, which seemed so wasteful. I then realized that I prefer roll-on medications because they are quicker, more convenient, less messy, and portable. However, not all my medications are commercially available as a roll-on (that I am aware of, anyway). I then decided to search for a refillable roll-on style container on Amazon that I could fill with my topical medications. They just arrived today and I had to test my idea out--and it worked exactly as I'd hoped! Now I can have roll-on topicals available for work and for home that do not require wasting gloves or washing hands to apply! My executive dysfunction and achy body are thankful for this find!

Bought these for the Crystal liquid spray on deodorant to get more control in the creased bits but the ball leaks around the edges leaving me pretty soaked. They probably work great for thicker liquids as I see on other reviews.

Does what I bought them for. Can be used for various liquid items. But will not work well with thick cream.
