Perfect for my needs

I have very small fingers and all my rings spin which is annoying plus I worry about damaging the stones. Regular ring guards didn’t help. The Ring Size Adjuster was perfect especially since I put it on after my rings were on my fingers.

Thank you Linda!!


Fits my rings perfectly & great price for the amount received.

Thank you Sonja!

Everyone needs these

When you order online a find out you don’t know your ring size after all, these are great for changing sizes to fit the finger you want to wear your rind on…provided your not trying to go up in size. If you have spent hours looking for the perfect ring, only to find out they only have it in a size 7, and you need a size 6 these ring binders will help make the size 7 fit your size 6 finger. They work great with real and costume jewelry, too!

Linda, Thank you so much for the amazing review! I can't tell you how much reviews mean to a small business!
