會田茂一

I’m using 0.8mm.
It’s a bit harder than the medium, yet not harder than the “hard”. The elasticity makes it fits tight and that is something I have never experienced.
When introducing to my friends, I always tell them “this actually is made of recycling PET bottles”, like as if it’s my invention 😉
The sound, feeling, concept,,,every character of this product is amazing!
