24 Grand Parfums® Stainless Steel Metal Balls for Rollon Bottles 24 Units - Replaces Roller Tops for Roll-on Bottles with Stainless Steel Metal Balls. Fits Our Standard 10ml and 5ml Roller Bottles

I love these toppers! They have replaced all my plastic rollers and I only had one roller that didn't fit these toppers. All of my vivaplex brand glass roller bottles fit with these just fine. I did have to screw the black covers on over the tops to get them to snap on all the way. They are a snug fit but I love how when I use them the oil glides on my skin like butter. I can't believe I ever thought the plastic rollers were good enough!

These roller balls are great! I bought them to replace the crummy ones in my old essential oil tubes! These fit very well and I can vouch that they fit on 10 ml tubes other than just what the company owns, so honestly the other reviewers much be doing something wrong... mine fit just fine with no leakage.These are so much better to use than plastic balls and they are at a very fair price. If needed, I would absolutely buy them again.

Just as described. Replacement roller balls for my jar of essential oils.

I don't think I've EVER written a bad review, but I must say I am VERY disappointed in this item. I bought these because I heard they were better than plastic roller balls which normally tend to leak over time. WELL these are HORRIBLE! the roller balls just FALL OUT after a day or two. At first I thought maybe it was just a few bad ones, but now it's happened to all of them.

Actually, when they work they are great. Much better than plastic ones. However, they're a little snug for the standard roller bottle, and I have had a few duds in the batch, leaking, & ball falling out. That's why I have them a 3 instead of a 5. Essential oils are pricey and loosing 1/2 a bottle due to a dud roller is a bit frustrating. Honestly I never contacted the seller with this issue. I have a feeling they would have replaced the items, but like I said, I didn't ask.

Works great! Only had one that the ball would not stay in.

I like the fast service and the product quality. I use them with my essential oils.

I purchased these because the non-metal roller balls I had would fall out after a while. These balls fall out after a week or so, even faster than the plastic ones I had before.
