Features
- Important to Know Always choose the correct size for a snug fit. If the adjuster is too small, it won't grip properly. If it's too large, it may feel loose and fall off
- One Pack Includes 8 clip-style ring adjusters in 8 different sizes, designed for flat band rings from 1 mm to 8 mm wide. Reduces ring size by 0.51 size
- How to Choose the Right Adjuster Measure your ring width using a ruler. Choose the adjuster that matches your ring width for a secure fit: Size 1 for 1 mm rings; Size 2 for 1.5 mm; Size 3 for 2 mm; Size 4 for 3 mm; Size 5 for 4 mm; Size 6 for 56 mm; Size 7 for 78 mm; Size 8 for 8 mm wide rings
- Secure Fit That Stays in Place Snap the adjuster onto the inside of your ring and press firmly until you hear a "click." This ensures it stays securely attached and does not fall off with daily wear
- Ring Sizers for Loose Rings Ideal for wedding bands, engagement rings, and everyday rings. Perfect for weight loss, seasonal size changes, or fingers slimmer than the knuckle
- Keep Rings Safe & Secure Prevents slipping, spinning, or falling off while maintaining a comfortable fit. Temporarily resizes your ring without damage
- Designed for Flat Band Rings Not compatible with round or square bands. Works best for rings up to 1 mm thick (sizes 15), while sizes 68 fit thicker rings over 1 mm. Use our coil adjuster for round bands
- Comfortable & Skin-Friendly Made of flexible TPU material, ensuring a comfortable, invisible fit for daily wear. Safe for sensitive skin

It works! I bought a ring that was a little too big, it fit at the time but my finger must've been swollen lol anyway I ordered these adjusters and they work! When I first put it on, it held secure for a couple weeks, then it seemed to loosen up a bit and began to spin. It comes with a couple different sizes/ thickness so I might try the larger size. It also comes with extra, enough to add to several rings. I love that it a clear color so you don't really notice. It's a great value for the price.

Where has this product been all my life? The metal ring sizers I've worn dug into my flesh and had to be removed when my weight changed. The silicone is easy to put on and take off, you can wash your hands with it on no problem and stabilizes my loose rings perfectly. I've been able to wear like 4 rings that have been unavailable for years by using this product. I love it.

They work awesome and they’re easy to adjust and don’t come off. The only thing is it turns brown after a week or two

These transparent, colorless plastic ring adjusters are comfortable. Each adjuster is a long coil you cut to the length needed. There are twelve coils in a couple of different widths. You wind the ring adjuster around the shank of the ring until you have enough loops for the ring to fit well. One or two loops more or less can make a definite difference in the fit of the ring. Then you cut the soft plastic adjuster with scissors. You can easily unwind a couple of loops to cut off if necessary or cut a few more loops off a longer piece to add if that will fit better. It is simple to unwind the adjuster if you want to remove it.

My engagement ring is my correct ring size, but it turns and doesn’t stay straight during the colder months. This kit was the perfect solution! I really appreciated the included sizing guide and instructions, and it only took a few minutes to apply the correct size and for my ring to stop turning! I love that I can’t feel the difference with the sizing adjuster on, it’s nearly weightless and doesn’t cut into my finger or hand. It doesn’t feel any different than having my ring on without the adjuster. Highly recommend if your finger size fluctuates seasonally!!

I could not be more satisfied with this purchase. For the price and what it is, I didn't expect much, but wanted to try. I was given a very sentimental ring and did not want to have it resized. I wrapped one of these around the bottom half or so of the ring, and it's absolutely perfect. The package has several more pieces I can use, I don't know if I'll need them. The material is extremely durable, comfortable on my finger to the point I don't even know the wrap is there. My ring fits perfectly. 10/10 I recommend!!

These things are great! Ive searched and searched for a good snug guard that won't breakdown tarnish or shift around or anything else weird and couldn't ever find one that worked and lasted until these little plastic guys! They work perfectly and you can't even feel it on your finger it feels natural yet and makes the ring fit snug! If you lost weight or your ring is just too big order these they actually work!

This works, but the annoying thing is that the product itself moves around on the ring, so now I'm either straightening my ring or moving the coil to keep it on the bottom where you can't see it. I'll continue to use it for now, but I may ultimately look for a different solution. I will say, you get a lot of product with this and just trim it down to the size you need, so this should last for a while and was a good deal for the price.
