For no reason other than how much I like it.
[edit:]The set is:
- Shinkaya goban 3 cm thick, 45 x 42 cm, with milled lines and 13x13-board on the other side.
- Yunzi stones biconvex, 8.3 x 21 mm
- The bowls are jujube (date(-palm) wood thanks for the info, bonobo)
- It comes with a strong carry bag for the bowls and I bought another one for the goban.
I bought it in http://www.hebsacker-verlag.de/, suggested by Boidhre in another thread.
