TORRAS Magsafe compatible smartphone ring. The ring can be used as a stand, and you can also put your finger through the silicone band. I purchased it about a year ago for 3,380 yen, but after using it for about 3 months, it didn't suit my needs, so I've been storing it at home. A metal ring that can be attached to non-Magsafe devices is included. Reference: https://torras.co.jp/products/omniring?variant=47913731129625 Thank you for looking.
