My wedding band is a little loose on my finger but I don't want to resize the ring because they'll cut off a part which they will not give back and we'll sort of lose out as we paid for the exact gram of the ring. Anyway, I've heard of these things called ring guards which can be plastic or metal to make the rings fit better on your finger. Most of what I found are from overseas. Has anyone else heard of this and is it available here?
