Can anyone here say what wedge these custom ones are based off of?

I can’t. But if you feel that you want to move them on, let me know 😄

Looks similar to the T7

These were collaboration between Mizuno and Alpen/Golf 5 which is a big box golf chain in Japan.   Super high bounce and a bit of a offset in the neck which seems to be the trend with wedge designs lately in Japan. 

Thanks everyone got it!
