Ring Size Adjuster, Clear Ring Sizer with Polishing Cloth, 2 Sizes 2mm and 3mm Fit for Any Rings, Perfect for Loose Rings by Fezep

I had to use these until I got my engagement ring resized and they worked nicely but it was really hard to take my ring off. I had to take the spiral off first. And it's not very cute and totally noticeable that you're wearing them despite the clarity. They also leave an indent in your finger.

Didn't realize you would get so many items. It's enough to use on many rings. I plan to give some away since I wont need all of them. These are very comfortable and easy to put on and so much cheaper than going to a jeweler and putting on the metal ring sizer or having the rings resized.

How did I never know about these fabulous ring sizers? Works perfectly! No scratching your ring. Soft and comfortable. Very easy to apply.

Doesn't fit most my rings to small for most of my rings

Work great

Seems fine haven't used them yet.

I was quite skeptical about this product but much to my surprise, even I could put these on my rings. Great idea!!

I have only used it on one ring so far and am happy with the results.
