Feramox Ring Size Adjusters are pretty useful if your rings are a bit too loose. According to the manufacturer's description, they come in sizes ranging from 3mm to 8mm, so you've got some flexibility in adjusting your rings. The package includes 48 pieces, so you'll have extras for replacements. They can reduce your ring size by 0.5 to 2 sizes, helping keep your rings snug.
These adjusters are made from soft TPU material, which is gentle on the skin and meant to be comfortable and non-irritating. They're also transparent, so they stay pretty much invisible once attached, keeping your jewelry's look intact. But to get them working their best, they need to be applied and used correctly.
From our research, it seems many people feel they work well, particularly in dry conditions. However, when it comes to being waterproof, there's a bit of a catch. Some folks have mentioned that the grip might weaken when wet.
So if you're washing your hands a lot or your rings get wet often, you might have to switch out the adjuster more frequently.
Besides needing adjustments sometimes, a lot of people appreciate their comfort and low profile, which often makes up for any water-related hassles. So, they seem like a good temporary solution for loose rings if you can avoid getting them too wet for the best performance.
