## Questions & Answers

**Q: I don't use lotion on my hands, but I sweat a lot. 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.
