No hassle fitting, clear plastic so no one can see
Plastic ring size adjusters are little clear loops you stick on your ring to make it fit tighter. Got a ring that’s a bit too loose? Just slide one of these babies on the back, and bam! No more wobbly ring.They’re clear, so no one can see them. They’re also cheap and easy to put on—no tools, no fuss. They don’t hurt, and you can still wash your hands without taking them off.Basically, if you don’t want your ring falling off but don’t want to resize it, these are an easy fix.

Sensible
Sensible solution for rings that are about a half-size too large. Clear and comfortable, and they clasp on snugly to the ring without collecting too much gunk over time. Pleased with our purchase overall. My husband’s adjuster fit easily on his wedding band. For my stacked rings, I only needed to place one on the top band, which then secures the one(s) beneath it quite well, without tightness. Best value if you have various rings of different thickness that you want to adjust. Still, the downside to this item is that there are no multiples or replacements in the size you need, so if one gets damaged, or if you only need 2–3 from the set, that £10 price tag seems a bit excessive for mass-produced bits of nail clipping-sized plastic.

Brilliant little plastic lifesavers!
I recently got engaged and my ring is very slightly loose and I was terrified of it falling off until we make the appointment to get it resized. These little plastic clips have been a bit of a lifesaver and made me feel more at ease that my ring won't slide off!You can see from my picture it's barely noticeable and I also can't feel it whilst wearing it

Good temporary solution to a ring that is slightly too big
Really good solution for ring half to one size too big. Really only needed one of the pieces as none of the others fit properly which makes this quite an expensive purchase. Having said that better than getting the ring sized particularly as my fingers do swell in the heat.

Sizes too small
When I opened the packet I couldn’t find a ring clip to fit my ring they were all too small. Do you make them any bigger to fit broader rings??

Perfect. Invisible. Comfortable.
The media could not be loaded. Really great product. I needed one for my ring that I got as a graduation gift. It’s something that I wanted to keep on all the time and never take off. This product allowed me to wear my ring and know that it’s not going anywhere.While they’re not the easiest to put on, when they are on, you just KNOW that it’s not going anywhere. I’ve been on nights out and just going about my day to day life and my ring has stayed put because of this product.It comes with a lot of different sizes for lots of different rings so you’re very likely to find one that will be right for your fit. I really can’t feel it either, it’s super comfortable and just feels like my normal ring without the ring sizer. My mom really wanted me to wear my ring to so when these arrived I sent her a video of how good it was - I’ve attached it, enjoy.
