I was hoping to get some direction on where I could find a 19x19 board like the one Curtis Tang can be seen playing on at the 1:05 mark of The Surrounding Game Trailer (The Surrounding Game (2017) - Official Trailer - YouTube). I really like the look and thickness and hope maybe some nice people here could help me figure out where I could get one.
Few online stores i’ve heard people recommending (first 2 in NA and other 2 in EU)
It looks like a typical thick table goban. You can find these from a variety of retailers, like the ones @_KoBa mentioned.
Also, here are some other retailers based in Japan
