A cheap, easy way to size your finger.
Note: The price for this ring sizer is $5, but because Squarespace does not offer custom shipping options for each item, you end up paying $5 for shipping so that is why the sizer is listed for $0.00.
"The Multisizer works like a belt. Simply push the end through the buckle to form a ring shape. Slip the Multisizer onto your finger. Adjust to a comfortable fit, checking that it just slips back over the knuckle. When best fit is achieved, read off size indicated by the arrow. (size 7 shown on the front of the package)"
Works for USA sizing 1-17.
