• •Universal: HiFan glue flexibly fills excess space in loose ring, then quickly cures to provide a perfect fit on your finger. Compared to fixed form adjusters, it is more suitable for rings of various shapes and sizes, will not fall off, and you do not need to install frequently, and ring will not be lost
• •Invisible, Comfortable: No toxicity/odor/color transparent adhesive seamlessly cures with inner wall of ring, keeping it smooth, non irritating. It won't slide, rub/clamp/cut fingers. Unlike bulky clip/loop type plastic adjusters, it is invisible, safe, comfortable, durable, and keeps clean
• •Easy to Operate: Apply glue in small amounts multiple times evenly on inner wall of ring, then irradiate it with UV light for 30-60s to accelerate curing. Slender outlet allows for finer glue coating, no excessive extrusion and waste
• •After Simple Disassembly, Ring will Not be Damaged: Soak ring in warm water for 5-10 minutes, then easily pry open glue block with a sharp but not hard object. Also try rubbing alcohol to make glue come off. No residue or scratche on ring, not need to clean
