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.

Comfortable and cut to size
My ring was half size too big, and I wanted to change up from the twist on adjusters (also from amazon) since it was uncomfortable and pinching my finger. Decided to try these that easier slip onto the ring and its so much more comfortable and you can't see the adjustor at all. I use the XS size and cut it in half (since original seemed to reduce it by 1 size down which was too tight for me). Worked well! Have also tried another amazon 'top rated' ring adjustor (the one with the curved grips) but that was way too big/tight when putting onto my XS ring, plus more suited for larger/men's rings where you need it to be at least 1 size down.

Amazing!
Can't tell if soft plastic or hard rubber, but either way, they work really nice, got them on 3 out of 4 rings, If you are actually looking for something there, then you will see it, however majority of people won't even notice. Another good thing about them because of the material they are made out of, it actually grips onto your skin, So when you wash your hands they don't slide off your finger.

Not that great
Only one of them fits the size of the band of my ring. It does help with the ring being a little big but it also moves around the band and sometimes ends up on the side of the ring instead of the bottom. Wouldn’t recommend.

These adjusters stay on well
Comes with a good variety of sizes. The adjusters stay on properly, because the sides curve up and slightly round the ring. They are nearly invisible.

Not fitting
This was so rubbish and didn’t fit my rings

Not cheap but worth it
These aren't cheap but they are great quality. They clip and hold onto the ring, and don't move around too much. They also haven't yellowed or caused any skin issues after long term wear. Cheaper ones I've purchased haven't lived up to the bar these set.

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.

Après avoir essayer plusieurs, je confirme que ces réducteurs sont parfaits. Ils se clipsent et s'ajustent à votre anneau. Assez discrets par rapport aux autres Je recommande même pour ceux qui ont des petits doigts

This little piece of clear plastic fixed the problem. My ring fits now and doesn’t twist around. Can’t notice it on my finger.

Hat definitiv geholfen. Jetzt passt der Ring bei meiner Verlobten wieder.

Received one that has totally straight 'walls'. Nothing that clips around the ring all. Not at all as pictured and does not stay put! Old version.
