Will they yellow from sweat? How many of each size in a package?** A: No yellowing! They are all different sizes so you can find the perfect size. They are clear plastic and do not show at all! They keep my tings in place perfectly. 5 stars! **Q: Some reviews mention an adhesive with this product, while other reviews say there is no adhesive. Which is it?** A: There is no adhesive. These are various size inserts. They are flexible plastic. **Q: This wont damage the ring itself in any way will it? If i wash my hands alot rusting wont occur?** A: I found that this particular supplier had the best fit for my ring. The other competitor's one that I tried kept falling off (especially when washing my hands) and didn't fit the ring properly. This one has not fallen off and fits fits perfectly - I have no fear of that the ring will fall off. The adjuster is made from a soft plastic and won't damage the ring. There shouldn't be any rust unless your ring is rusty! I would recommend this manufacture's ring adjuster. **Q: Not familiar w/ these. It looks like you would have to put it on the ring before you put the ring on your finger. How will it fit over your knuckle?** A: You slip the adjuster on the ring after your ring is on your finger and past your knuckle. There will be a space between your finger and ring...slide the adjuster on to your ring. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***Y on March 28, 2026* ### ⭐⭐⭐⭐⭐ Review *by T***E on May 1, 2026* ### ⭐⭐⭐⭐ Review *by R***L on November 12, 2022* ## Frequently Bought Together - Invisible Ring Size Adjuster for Loose Rings Ring Adjuster Fit Any Rings, Assorted Sizes of Ring Sizer - Ring Sizers for Loose Rings, Eiito Ring Size Adjuster Spacers or Tightener, Invisible Guards, 6 Sizes Fitter, Resizer Fit Almost Any Rings, Reduces Size by 0.5-1.5 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/63255207-invisible-ring-size-adjuster-for-loose-rings-ring-adjuster-fit](https://www.desertcart.us/products/63255207-invisible-ring-size-adjuster-for-loose-rings-ring-adjuster-fit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
