  • Convenient Removal: Effortlessly torn off the adjuster by gently prying it open with a hard plastic tool, leaving no residue or damage to your precious rings. For easier handling, refrigerate the adhesive for 5 minutes before use. This quick step thickens the liquid slightly, allowing precise application and a bubble-free finish. Combined with the UV light’s instant curing, it’s a hassle-free solution for perfect ring resizing every time.

Ring Sizers for Loose Rings,Kueroami Wedding Band Adjuster,Inserts for Rings that are Too Big,Make Smaller Without Resizing,Reducer by 0.5-2(Clear)

Why we love it
  • Invisible, secure ring adjustment.
  • Customizable for unique rings.
  • Safe, skin-friendly materials.
Main Highlights
  • INNOVATIVE DESIGN: The ring adjuster gel bonds securely to the inside of your ring, eliminating any fear of it slipping off. Even under close inspection, it remains completely transparent and invisible, blending seamlessly with your precious band. Each set includes 1 bottle of clear ring-guard adhesive and 2 XXS silicone ring adjusters—the perfect solution to preserve the integrity of your cherished wedding and engagement rings.
  • SAYING GOODBYE TO THE LOOSE RING: By controlling the thickness of the resin, the ring can be adjusted to any size you want, preventing it from slipping or spinning to one side. It is especially suitable for irregularly shaped rings and can also be used as an adjustable ring guard to prevent open rings from getting caught on hair or clothing, providing additional safety and convenience for uniquely designed rings.
  • SKIN FRIENDLY MATERIALS: Made of environmentally friendly materials, this resin is very safe for the skin. It is odorless, waterproof, and once cured, it will not peel or detach, providing a reliable ring shielding protective agent that can be used for bathing, swimming, and other purposes at any time.
  • EFFORTLESS SETUP: To find the perfect thickness, apply a 1mm layer of resin onto the inner wall of the ring and cure it with a UV lamp for 60 seconds. If more thickness is needed, apply multiple layers and increase the exposure time. In hot weather, refrigerate for 5 minutes before use to make the solidification process easier to control. Note: UV lamps must be plugged in during use and are not rechargeable.
  • CONVENIENT LEAK PROOF BOTTLE: Each bottle contains 10ml of glue suitable for various applications. Featuring a leak proof design, it prevents overflow and accidental opening, making it ideal for jewelry enthusiasts, ring collectors, and outdoor explorers.
  • USE TIPS: For the best results, store the glue in the refrigerator before use (please note that this is glue and should not be ingested). Lower temperatures reduce the glue's fluidity, making it easier to handle and apply.
  • EASY TO CLEAN: Wipe easily removes dirt, oil and grease, preventing moisture retention and contaminant build-up.
