Invisible Ring Size Adjuster for Loose Rings - 12PCS Adjustable Ring Sizers Fit Any Jewelry - Perfect for Wedding Bands, Engagement Rings & Fashion Rings - Secure Comfort Fit for Daily Wear

So glad I found this product! The base of my finger is a size ~3 and my ring is sized to a 3.5. This made the ring feel super loose and was constantly sliding / spinning around my finger in the most annoying way, especially while washing my hands.My ring’s band is ~1.4 (thinnest they can be?) and I used the smallest size in this pack which fit perfectly. The pack comes with 4 long strands of each size. The ring now fits much more comfortably, snuggly and doesn’t rotate at all. Seriously best $5 I’ve ever spent.It looks a little funky on pictures but it’s actually super small, subtle and helps the ring feel so much more comfortable. The ring now feels like “it is one with my finger” rather than slipping, spinning and flopping all over the place. I haven’t had any problems with callouses or discomfort.To put this on: I put the product on the ring and then lubricated it with lotion so it would slip over my knuckle. It was tight but it worked! It would probably be tough to put this product on while the ring is already on your finger, rather than putting it on the ring first and then putting both on your finger.To take off: I put lotion on the ring and product to slick things up and then grab one end of the spiral-plastic with my nails, pull hard and the spiral unwinds right off the ring, then I came easily take off the ring normally.
