I'd like a bunker ring.
I found this in a YouTube video, and I want, because my fingers is too short. If I use this, maybe I can use iPhone only left hand. Of course I can use both of hands, but I'd like to feel like a parson with long fingers.
But many similar item is on amazon.co.jp. If these has no difference, I can buy cheeper one. But cheeper is something wrong maybe. So I'll buy a bunker ring.
