Bflaae Ring Sizer Measuring Tool Kit, 27 PCS Stainless Steel Measuring Ring Tool, US Ring Size 0-13 with Half Size, 2 PCS Reusable Finger Size Tape with Magnified Glass 1-17 USA Rings Size

Nice and convenient to have on hand at trade shows, art fairs, and when the ring is on the other finger and I'm shopping for rings instead of doing sale. They are accurate and its great that they have 1/2 size measurements.

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.

This Ring Sizer came as advertised, and on time. It comes in plastic case so you don't lose any of the rings and small sizing straps. It came a great price; and did exactly as I wanted.

Accurate sizing. Sizes could be a little easier to read.

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.

They work and are made nicely. There are not any pocky areas. I like how I can use the measuring device for my husband and son. They have very thick fingers.

I love it when you get exactly what was advertised. I’m a getting a ring for a crypto wallet and have no clue what my size was or where to even start looking. I came across this product and it made the process so simple for me to use even by myself I used the plastic tool to get me close then I dialed in the exact size using the metal rings. But I still had doubt so I went to an actual jewelry store and they confirmed the same size this tool told me. So save your time and know this product is accurate, easy to use, and inexpensive. This was a good find for me and I’d definitely recommend it.

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.
