Bflaae Ring Sizer Measuring Tool Kit 27 PCS Stainless Steel Measuring Ring Tool US Ring Size 0-13 with

This ring-sizer kit is exactly what you need if you’re trying to follow Oura’s recommended process for choosing the right ring size. The stainless-steel gauge offers precise, clearly marked US sizes—including half sizes—from 0–13, which is especially helpful since Oura doesn’t offer half sizes and encourages users to test multiple options. The inclusion of two flexible tape-style sizers (one with a built-in magnifying lens) is surprisingly useful for quick checks or for comparing fingers on both hands. The magnifier is a thoughtful touch and makes the small markings easy to read. Most importantly, the kit makes it simple to follow best practices: wearing the gauge for extended periods, testing different fingers, and checking fit during morning and evening when swelling shifts. Both my wife and I have worn different steel gauge rings on each hand overnight and throughout the day, and this kit made it easy to see how dramatically finger size changes with temperature and activity. For anyone sizing an Oura Ring—or any ring that requires a snug, sensor-reliable fit—this inexpensive kit removes the guesswork and provides reliable, repeatable measurements. Read more

Absolutely necessary for verifying ring size. You don't want to make any mistakes when buying custom online and this measuring kit is so affordable. The sliding strips will find your size, but but the metal ring measuring set allows you to wiggle and pump your fingers to really make sure you have the right size. Finger sizes change over time, so always handy to have around, but even if you use this one time, it's well worth it. Read more

I bought these to determine our ring size for our wedding rings. They look exactly like the kind of set that a jewelry store has. It was able to very accurately determine our ring sizes which made it so much easier. The ring sizers are also extremely sturdy and have a weight to them that suggest high quality in my opinion. They're easy to put on and take off, not sharp at all. Overall, I can recommend these to anyone looking for an accurate ring sizer. Read more

The media could not be loaded. This set of ring sizers is awesome and something I've been needing for a long time. Why it took me so long to realize that I could just hop on Amazon and buy one, is beyond me. And so inexpensive too. Of all the expensive items I buy , this inexpensive yet very valuable ring sizer, is definitely my best investment.. Finally I know the ring size for every single finger on both hands. I had no idea that my middle finger, index finger and thumb finger, were all the same size. They may not have always been the same size, but I'm older, post menopausal, live in a hot and humid climate, so my hands and finger's do tend to swell. They recommend measuring your fingers multiple times throughout the day as we can retain fluid and swelling can cause a slight variation in size. The ring sizers come on a steel loop holder, with sizers ranging from 0-17. And the best part, they measure half sizes. Yay!! The accuracy is spot on. Also included with this product is a tiny magnifer. There's two (2) plastic strips included, a black one and a white one. The black one is the magnifer and how you use it is by sliding the open end of the magnifer over the # label on the different ring sizers. (See video). The White strip, as well as the black magnifying strip, both have #'s printed on them so you can use those too as a ring measuring tool. This whole kit is awesome. Looks very similar to the ones you'll find at the jewelers. I'm beyond elated with this. And for the price, it makes it that much more appealing. Read more
