Smartphone holder / Smart phone hand holding tool "Magoyubi Early type" (孫指初期型)

#overview
I made a tool to help hold a smartphone.
With this tool, we can protect our fingers from text thumb damage.

#How to use this tool
1. Put the circle of this tool into the ring finger.
2. Then put your little finger in the semicircle.
3. Put your smartphone on the L-shaped part.
This basic idea was based on Matsumoto Keiji's Twitter idea.
