KEEP RINGS SECURE: Keep loose engagement rings, wedding bands & other rings from falling off or sliding around. Our adjuster is an inexpensive solution that keeps precious jewelry in place and looks great!

20 SIZERS - BE SURE TO MEASURE CAREFULLY: Our adjuster inserts directly under your ring to adjust the fit. The pack includes a total of 20 adjusters (4 X-Small, 4 Small, 4 Medium, 4 Large, 2 X-Large and 2 XX-Large)
EASY TO USE: Simply bend and hold the adjuster for 3 to 5 seconds before using so the material can set and conform to finger. Unlike tighteners that need to be cut and cannot flex, ours fits comfortably.
JEWELRY CARE KIT: Along with the 20 Adjusters we also include a Cleaning Cloth, a Travel Pouch, a Cleaning Brush (CLEANING LIQUID NOT INCLUDED) and a Ring Sizer. With all of these extra accessories you can make sure that your jewelry shines and is kept safe! The Ring Sizer allows you to measure ring size for any finger, so you can shop with confidence!
