## Description

Ring Adjuster for Loose Rings - 12 Pack, 2 Sizes - Ring Size Reducer, Guard, Holder - Spiral Silicone Tightener Set with Polishing Cloth : desertcart.co.uk: Fashion

Review: Secure rings safely. - Perfect! Just as described. These were very easy to fit. Feels comfortable. Rings fit snugly, but can still be taken off. Attached to two new rings I bought to replace the loss of a ring of great sentimental value. Wish I'd known about these before. Delivery spot on time. Definitely recommend.
Review: Invisible, Comfortable, and It Works - These ring sizers are completely invisible when wearing them. They are so comfortable that you cannot even tell they are on. The pack comes with clear instructions and a handy cleaning cloth. They stay securely in place during everyday activities and household chores, like cleaning. While I have only used it on one ring so far, I can tell it would work well on other styles too. It is a very useful and affordable alternative to getting a ring permanently resized by a jeweler.

## Questions & Answers

**Q: Are these noticeable when you turn your hand over**
A: Thanks for the question. Yes, they are noticeable and they are not 100% transparent.

**Q: My sons ring is about 3-4 sizes to big will this product help**
A: This is only my opinion but I don’t think these will work for a ring that is 3 to 4 sizes too big unfortunately. My ring was approx 1 full size too big and these are great for that. I used about 3 or 4 rubbery rings to make it tighter and it’s fine now however I’m unsure that they will be enough to make a ring 3 to 4 sizes bigger, fit. I’m not a jeweller but know a little bit about jewellery. It may be better to have the ring resized instead which I appreciate will incur a cost. They can usually resize up to 3 sizes up or down but it’ll depend on what type of ring it is. Sorry I can’t be more helpful but hope this might give you some assistance.

**Q: Can these be used for a thumb ring that is slightly loose**
A: can be used on any ring

**Q: Can I put it on once ring is on? Big knuckles slim fingers**
A: Unfortunately I don't think you will be able to. You have to wind the plastic around the ring.

### ⭐⭐⭐⭐ Good adjuster which does as advertised!
*by J***J on 8 November 2025*

Works well to reduce ring size, easy to cut and fit. Good wearability, although would be nice to have options of different thickness so less obvious when wearing.
