Euro Ring sizer, to measure your French ring size
The Euro 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 give a comfortable but not to lose fit, checking that it will slip back over the knuckle. When best fit is achieved, please read the indicated size. You can re-use it as often as you like. But please keep in mind it's plastic, so can brake with time. A cheap but reliable way to find out your Ring size. This one will indicate the French / Europe ring size. I have also the UK one on offer.
