ELETIUO Filled Metal Ring Guard Set for Loose Rings, 12 Pack 3 Sizes for Different Band Widths, Invisible Ring Adjuster Tightener Spacer Fitter, Golden+Silver Color

Works for me.

The metal pieces are thin and cheap, once I got the piece on my ring and tried putting my ring on, the metal would bend and conform to the bottom of my ring.

Purchased a new ring and at the store it fit ok. Few days later it started to feel loose. The ring would Come off while washing my hand. Decided to buy this ring size fixer and took a set of pliers and installed it. It works great.

Lots of different sizes but all metals too big( wide) . Used one plastic curly one but it’s not what I wanted.

Nice for the oversized rings so you don't have to take it to a jeweler and have it sized down, losing precious metal in the process.

Bought for a friend. She found them easy to use.

Too thin and flimsy, it will just bend to conform to the ring and not do a bit of good. Mine were returned.

This works really well. Is not noticeable like the plastic ones
