## Questions & Answers

**Q: I have a really wide ring it is 13.5 mm, will any of these fit that size?**
A: The pieces that sort of just clip on to the back we’re uncomfortable for my husband on his 10 mm ring and I was able to put the twirling piece on it and that was better, but you do have to stretch out the loop more to make it wrap around than on a smaller ring, but you can still make it wrap around. It was bulkier, but it was more comfortable than the other piece for him. I haven’t tried the foam adhesive pieces yet.

**Q: Will it reduce a size 12 ring to a size 8?**
A: I think so…I was able to take a size 9 ring and with this product, I was able to fit it securely to my size 4.5 finger

**Q: Are they all easily removable? And wont damage the ring when or if my finger swells**
A: Yes, they are all easily removable. My grandson uses different ones on rings for different fingers. They are plastic so no damage.

**Q: I never received this item. How do I get my money back?**
A: Go through Amazon returns. Go to your orders, choose the item and then there should be an option to chose return.

### ⭐⭐⭐⭐⭐ Perfect Solution For Me!
*by A***O on June 1, 2025*

McKanti 100 Piece Ring Sizer:I had my jeweler made me an 18KT White Gold Croix de Lorraine ring with a black onyx background.I had it made about six years ago. I am an athlete, and from the time I had the ring made to about three years ago, I lost more fat due to my intense training, and the loss of weight made my right ring finger smaller; hence, my Croix de Lorraine ring became too big for me, and it kept slipping off.Sadly, I only had two alternatives:- Cut the band to resize, or- Have a whole new ring made.I was gonna have a whole new ring made; because, cutting the band to resize it did not appeal to me AT ALL.I prayed on it, and I was guided to this product:McKanti 100 Piece Ring Sizer.Today, 31-May-2015, at 1630 hours PDT, the McKanti 100 Piece Ring Sizer arrived.Immediately, I tore into the package, and I found the plastic ring spacer that perfectly fits the band of my Croix de Lorraine ring, and BAM! It fits; and, my ring now fits my finger!The spacer stays secure on my ring and finger; it is comfortable, and it’s easy to put on and take off.It appears to be durable; with the 100-piece set, there are extra spacers; hence, if I lose the one I’m using, or it degrades, I can easily replace it with one of the extra units.I am very happy with this solution.See attached pictures!/s/ Alfonso Faustino

### ⭐⭐⭐⭐⭐ Fantastic cheap & quick solution to an ill-fitting ring!
*by C***S on November 15, 2024*

Funny story - got my wedding ring specially made for my size finger and the jewelers got it wrong lol. Had to find a solution for it and this worked well!I don't think the plastic clip-on things work. They don't have enough of a lip to grip onto the ring tightly, and only work if you really guide it onto your finger with the ring (takes a little effort to do so maybe not for everyday use).I personally also wouldn't the foam stickers in this kit. I will say though, they give you a lot of sizes so you can find the right one for your ring. However, all of the strips are the same girth, so if the foam strip isn't thick enough to make the ring fit on your finger, then it won't really work. Also I would be concerned for it coming off if you get the ring wet.The plastic springy things worked great though! Pretty easy to install and they seem the most durable. The other options may fall off if you tried removing the ring. The springs come in many sizes and you can adjust the length of the spring on your ring.Good Tip!! - if you want to make the ring fit more snugly, then add a longer springy thing to your ring, rather than a short one. The shorter ones make the ring fit less tight, longer ones make it fit more tightly.

### ⭐⭐⭐⭐ Did the job well. I'm happy with the overall product.
*by R***. on June 14, 2025*

The spiraled resizers worked great and are comfortable enough. The velvet resizers didn't adhere properly with my rings but would have been perfect if it did. The clear flat ones didn't quite work with my rings but weren't bad.Everything else was great in the kit.
