MagicHappens Empty Refillable Roll On Bottles – 50ml Leak-Proof DIY Deodorant Containers with Plastic Roller Ball, 2pc Set

These work perfectly. No leaks! I researched the comments of all the bottles on amazon, and was satisfied with the comments here, so I gave it a try. What most other products had complaints about was leaking and poor quality. These don't have that issue. There's a screw on top. Nothing leaks through that or the ball area. And the ball rolls beaitifully! Very satisfied and highly recommend!

I like this product. I fill it with milk of magnesia and use it as a roll on deodorant. It slides nicely, does not pinch, does not leak. Great seller. Item arrived quickly and was well packed.

You get what you pay for! Make sure after you remove the cap that you tighten the roller. Mine have popped off twice and spilled the entire contents.

These definitely leak. Every time I pick up the bottle to use it it has residue on the outside that has dripped down the side even after the cap has been screwed on. I don't know if the ball is too loose or what but it wastes the product you put in it and makes a mess.

It is perfect, I using for a liniment for my aching back so I won't have the smell in my hands. No leaks as reported by some. Make sure to remove cardboard piece behind rollin ball... Duh!

Flimsy and didn’t hold liquid well.

This was a meh product. The plastic is too thin and had difficulty getting the product to come through the roller ball. I replaced these with glass ones. Hopefully Ill have better luck with those.

GREAT
