Manufactured in the US, the RinGuard ring size adjuster/reducer eliminates problems through its innovative spiral design. The spiral allows for the RingGuard to fit comfortably, and flexibly, to nearly any ring. Unlike tube-based designs, the spring/spiral RinGuard will not retain water or dirt and fits a wide variety of ring shapes and sizes. Don't lose a ring, or wear an uncomfortable, inferior, ring adjustment product. Keep your ring comfortable with a RinGuard.
