It's a curious thing, that so many of the important little cards in our wallets are so often unreadable. So make sure your wallet is also equipped with this card-sized magnifier, engraved with tiny ridges that function like a lens to enlarge any tiny text you may encounter. At just over 3¼ × 2 inches, it can be tucked away wherever you keep your ID and credit cards. A vinyl storage sleeve is provided to help keep the magnifier in pristine condition.
