IT'S HERE! We finally offer biconvex stones AND we are offering them in our new locking hard plastic bowls! These stones have a decent weight to them, not as heavy as glass, but enough to make that loud satisfying snap when you play a game-winning tesuji.
The stones are melamine, 9.5mm thick and 21mm wide (perfect for any standard-size Go board). Most importantly, the double curved nature of the stones make them easy to clean up after a game is finished (so you can quickly run to the restroom and cry about your latest self-atari).
These are also perfect for tournament settings were you can get yourself into a flow state by plunging your hand into the bowl and losing yourself in the satisfying silky smooth feelings; all while driving your opponent (and everyone else) completely mad with the noise.
The bowls are durable plastic and the lids twist to lock. So while you confidently stroll into club ready to beat down that new guy for the 5th time this month, but then your butterfingers drop the bowls... well the stones won't spill! and you can try and swoop them up before anyone notices.
Joking aside, we've been trying for quite a while to get biconvex stones that don't suck. Now they finally are and all you cultured Go players can experience them. Enjoy!
