6PCS Upgrade Ring Sizer Measuring Tool, Accurate Ring Sizers for Loose Rings, Premium 1-17 USA Ring Sizer Tool, Easy to Use Tools, Jewelry Tools, White and Black, Reusable, Comfortable Plastic

They're accurate as far as I could tell! I had a rough estimate of the ring size for a couple of my fingers, and it seemed to give similar results to what my guesses were based on ring sizes I own.Also, fret not as it doesn't "lock" like a zip-tie does, so your finger isn't going to get stuck.

This ring sizer is pretty convenient to use and measures accurately enough. I think this is the best tool to use to purchase ring online. The print on the ring sizer is clear and the design is pretty nice. I would definitely recommend this to my friends.

I tossed one in each glove box. I can grab anyone's size in a second no matter where I am.

I'm glad I bought six of these instead of a set of metal ring sizers that reviews say are inaccurate. Also glad that don't have to rely on measurement tape or a printout from a computer. This adjustable gauge slides on and off a finger easily...or with difficulty! You don't know which size ring to order just by the circumference of the spot on the finger where you are going to wear it: the knuckle can change the story for you!I noticed a review that said the printed increments wear off. I suppose the reviewer buys many, many more rings for many more fingers than I ever expect to. There is the economical option to buy six of these. That should solve her problem, but it leaves me with five extras!

I was needing a ring sizer and have been looking at a bunch of them but this one caught my attention. You get 6 of them so that's a good deal. They are very easy to use and do not take up a lot of room which is a plus for me. It arrived on time and well packaged. I am happy with my purchase.

I bought these to measure my family members' fingers for a signet family ring I am having designed by a jeweler. While I understand that a finger's ring size can change over a course of a day based on a myriad of factors and salt intake (lol), they were off from the professional jeweler's ring sizers and we tried more than one of theirs for comparison. Sadly, I am returning them because I couldn't trust them.

just needed a simple non expensive measure for rings. lightweight plastic bands, easy to read and works perfectly. arrived at its estimated time. very pleased

I found this awesome ring I wanted sooo much. I got these to check my ring size before I ordered. Nailed it at size 11. Ring fits perfect! :)
