Review: Perfect solution after weight loss. - These ring size adjusters can decrease the ring fit for your finger by .5mm to 1.5mm. They have an almost invisible design. It comes with multiple adjusters of each size. They are very easy to attach to the ring. It is just a clear coiled plastic that goes around the inside hand part of the ring. It can be clipped off to take up as much or as little ring surface as you need. These adjusters seem like they would last a long time. There is also quite a few adjusters that only need a portion of each to use so even if they get to dirty or something you have plenty of replacement pieces. Being that the adjuster is placed on the inside hand part of the ring it seems unlikely much damage would happen to it. I love the convenience of this product. You literally just wrap the coil around your ring and snip off the excess with a scissors. I also love how it’s not some bulky unsightly thing. It’s barely noticeable and that’s only looking at an open hand. Most people would think it’s just part of the ring. The only thing that I think could improve for this product would be some sort of included physical instructions. They include a qr code that requires a special app that I didn’t feel like downloading just for this. I didn’t have sizing instructions but figured it out myself pretty easily. My overall experience was great. I hadn’t worn my actual wedding ring for about 3 years due to losing weight and the ring kept dropping off my finger. I couldn’t justify spending the money to have it resized. I saw this product and the price was more than right to try it. It was so easy to attach to the ring and for the first time in years I’m sporting my wedding band which looks great. I would definitely recommend this product to my Family and friends if they need to shrink their ring size. Anyone who needs either a cheap solution or something to make their ring fit until they can get it resized will love this. This has to be the easiest and least invasive solution.
Review: Fantastic and Versatile Ring Adjuster - Edit to my original review: After wearing my rings with these coils for a couple of weeks, I realized that they have an added bonus benefit. If you are anything like me, your rings (especially solitaires) have a habit of slipping sideways on your fingers and you’re constantly having to straighten them. Once I added these coils to my rings, my rings stay put and they don’t slide around. I love this surprise feature! This package of ring-size adjusters is easy to use, full of enough little coils in multiple sizes to handle a TON of rings, is comfortable to wear, and a great value for the amount of product. Can’t say enough good things about these!

### ⭐⭐⭐⭐ Only two sizes
*by S***E on April 25, 2026*

These ring sizers are easy to install and look good with white gold or sterling. They stay in place well. My only complaint is that there are only two sizes in the pack. If they happen to be the size you're looking for this is a win. If not you wasted your money. They worked on most of my rings, so it was worth the price to me.
