This great blue plastic ring sizer will help you figure out your finger size(s) at any given time.
Weather/temperature extremes (winter, summer), weight loss and weight gain all affect the size of our fingers, so this really handy gizmo gives you a chance to size your fingers in the comfort of your home whenever you're ready to purchase a ring!
How to use:
Just snap out the various rings and try them on like you would real rings. The size is clearly indicated on the little tab attached to each ring (you see it well in person, not in the picture). Find the perfect fit for yourself and your family!
The rings in ring sizer are US/Canada sizes 2 1/2 to 14, in half-size increments.
