3-Part Stainless Steel Roller Tops – 12 Pack with Caps – Fits 11 mm (0.425") Neck Opening – For doTERRA, Young Living & many more 5ml & 15ml Bottles, & Revive 10ml Bottles – Leak-Proof, Rust-Resistant

these metal rollers work well, once you get it into the bottle with no leakage. Some have said they don't fit but I found with effort, you can push it into the bottle. The fit is very tight which is good but the fit might be too tight to remove it. This remains to be seen. I used a Metal Orifice Remover (you can get them here on Amazon) to assist in pushing down by placing the ball into a circle so that when I pushed, it didn't push the ball down into itself. The Orifice Remover is a handy tool to have anyway when removing caps. I gave this 5 stars because It is hard to find decent rollers for 5 & 10 ml bottles so it was worth the effort.

These are the perfect size to use on 5-15ml serums. Also works for oil essences. The rollers make it easy to apply serums. If you chill your serums, the steel ball has a nice cooling sensation when it touches your skin. Very easy to put on. Make sure you snap it in place. The cap is tight and stays secured. I've now replace all my small serum & essence bottles with these rollers. Highly recommend 🙌

Where were these 15 years ago when I started using oils? I've been painstakingly transfering them to teeny roller bottles all this time, which is timeconsuming and sometimes messy no matter how careful I am. With these roller fitments I'm now able to roll on any undiluted single oils such as lavender as well as all my prediluted oil blends straight from their original bottles, which is much more convenient. So far they've fit Young Living, Rocky Mountain, Plant Therapy, and Vibrant Blue bottles from 5-15ml. They're a tight fit, so you have to really push to get them in on some bottles, and I needed my little metal template tool to pry them out again. But they're not leaking at all, the roller balls aren't falling out, they dispense the right amount of oil (not too much, not too little, even on my back), and the large, well-sealed caps on these are easier to twist on and off than either the original bottles' or the roller bottles' caps. These are great and I'll be buying more of them.

I do perfumery, and have been having some issues with eczema, so wanted to make my *personal* perfume with an oil base rather than the perfumers alcohol I usually use, so needed roller balls for application... I use the Vivaplex 15ml bottles, and ordered these (based on the high reviews) hoping that they would work with them. I won't lie, I really didn't think they fit just now, when I first went to put them in, I could get them halfway in, and they were NOT budging.. I came here and looked at more of the TEXT of the the reviews and ended up almost giving myself a bruise pushing on the rollers, and they DID finally pop into place, so they DO fit.. But yeah, just be ready to put some massive elbow grease into getting them in. But they are stable now (and my perfume is fading a little weird, but... hopefully the oil base will stop irritating my skin, and this will be worth it.. lol)

I perched this product excited for roller bottles lol these fit no bottles I've tried so far. Revision, I did not have a tool didn't know I needed one till I perchesed a kit roller tops work great.

I love using these on my empty essential oil bottles. It is very cost effective.

I had tried and returned other roller bottle tops that looked exactly like these, but were obviously not as good of quality. These tops work perfectly to repurpose my used essential oil bottles!

It fits the doterra essential oil bottles great ! I use them for making my oils last longer by diluting them with the coconut oil. Hasn’t leaked out yet! Helping to save the planet by recycling.
