Ring Sizers for Loose Wide Rings - Invisible Clip-on Ring Size Adjusters | Fit Wide Rings Only, for Flat Band Width from 4mm to 10mm, Patented Clear Clip-on Ring Sizers in 4 Sizes

These work very well. Had to buy them for my husband's ring since he lost weight after the wedding and his ring is a bit small. Don't forget to use the double sided tape to stick it to the ring though or it will slide around and be uncomfortable.

These are perfect. They’re strong and solid. They come in a variety of sizes in one pack so it’s easy to find the perfect fit. The clear ones are nice because nobody ever notices they’re there. They’re essential for me because my fingers change size depending on the temperature. I can’t even feel it. I don’t ever even remember it’s there. They don’t stick, they pop into place which is nice. All I had to do was put the ring on just past my knuckle and snap it onto the ring. Took me about 5 seconds and I was all set. I’d recommend these to anyone who’s worried about losing their ring because they cost next to nothing compared to losing an important ring. Worth it.

Easy to use and slid right into my husbands wedding band! No more searching for his band when it flies off his finger!

Not very good, because the lip on either side of the sizer is way too thin, which means the sizer doesn't clip on well and can easily slip off when the ring is removed from your hand.

Perfect size. Easy to use. Seems to be good quality. Easy to take on and off of ring when hands swells.

Does not work well. Would not stay on wedding band. If you ever wash your hands this is a waste of time. Not durable, will not stay on

I wear the Ring Conn 2 sensor ring in a size 6 on my pinky. It was a bit loose (it came off once while doing laundry, and luckily I found it!). I was having trouble trying to figure out how to make it a better fit since the sensors are on the inside bottom of the ring. I was going to buy the glue adhesive, but I didn’t want to take a chance that it would ruin the ring. This set of ring sizers was perfect. Although I only needed 1 specific size, I placed it inside the top inner ring and snapped it in perfectly. It is now snug yet easy to take off, doesn’t ruin the appearance as it is clear, and allows the sensors to work accurately. I highly recommend this ring sizing set.

I love this product it’s very easy to clean I ordered the wrong size customer service was great they allowed me to exchange it that was awesome the quality is great he loves it
