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 ### ⭐⭐⭐⭐⭐ My saviour *by S***U on 9 July 2025* I lost weight and the ring was loose.
