These are FINALLY back in stock! This handy little apparatus lets you find your ring size over and over from the comfort of your own home! You use it just like a little belt and it justs slides right through the end. Pretty much like a zip tie that doesn’t lock. You will receive one ring sizing tool inside the envelope pictured with instructions on how to use it. The notches between the numbers are half sizes. For example; The photo on the hand shows the gauge at a size 6.5. I would recommend measuring your finger in the morning and at night for the most accurate reading, as fingers tend to swell throughout the day and make sure you take it on and off to make sure it will go past your knuckle once it’s sized.
