Avoid the hassle of exchanges and find your perfect fit with our Ring Sizer. The simple belt mechanism makes it easy for you to identify the correct ring size. Our easy to use ring sizer works like a belt. Simply push the end through the buckle to form a ring shape and use it to measure your desired finger. Make sure the fit is comfortable and that you can slip the belt on and off over your knuckle. The arrow on the buckle will indicate which size will fit you best (size 4 shown on model). To use the ring sizer: 1. Take the tip of the ring sizer and push it through the buckle to make a loop (it’s like a belt!) 2. Put the loop on your finger. 3. Once the loop is on your finger, pull the end of the belt to tighten the loop around your finger. 4. This next step is the most important - the sizer must be able to come on and off your finger (like a ring would). You should feel resistance when sliding it past your knuckle, but it should be able to come on and off. If this is possible, the ring fits - comfortable doesn’t mean loose. It’s important that the ring fits snugly, otherwise it will be too big on your finger.
