KONAFEI fasadf Ring Size Adjuster: Invisible design with transparent TPU material
Ever had a ring that just won't stay put? The Ring Size Adjuster is your go-to fix, tailor-made for Oura Ring Gen3 Horizon and Heritage—plus any other 7.9mm width rings out there. Crafted from top-notch transparent TPU, it's like a ninja for your jewelry: there, doing its job, but you'd hardly notice. It snugly reduces your ring size by 0.5-1 size, so say goodbye to those awkward moments when your ring decides to take a stroll off your finger.
Why you'll love it:
- Soft, skin-friendly TPU that's as safe as it is comfy
- Wear it all day with zero fuss—no pain, no irritation, just a perfect fit
- Slips on easy and stays put, no magic required
- Comes with 6 inner pads and 2 trays, because why settle for less?
Heads up: If your charger and ring are already in a tight embrace, the inner pad might crash the party (aka, interfere with charging). Might wanna grab a small-sized charger from Wonjoy store to keep things smooth.
- Reduces ring size by 0.5-1 size
- Soft, non-toxic, and comfortable TPU material
- Easy to use and stays well on rings
- Includes 6 inner pads and 2 inner trays
- Invisible design with transparent TPU material
