Go-game magnetic "stones" for commentary on TV

[Buntaro]

Hi everybody.

I used to watch Go games on TV in Japan. They would have commentators in the next room, using large magnetic "stones" on a large "whiteboard" for commentary. Has anyone else seen these magnets? Are they for sale?

Hi Buntaro-san!

I think you can buy it through Nihonkiin:

I think it's the one that is coded P08.
I don't know much else, so you'll need to inquire them regarding shipping, etc.
