Ok so unfortunately I don't have much (which mean anyway) info about this at the moment, sorry. I got this from someone as a gift just today/last night straight from the source. Now two player from there came out with this and the names given didn't ring a bell at the time, one of the names sounded like Lee He Wen but when i got a glimpse of the Japanese article or post or what ever it was the name wasn't spelt that way.
Opinion: I like it (i know, that's not saying much so relax) but in my personal preference for chalk i liked the texture which was not a gritty Master type chalk but also not that soft clay type think like Kamui. It stays on nice and when it become available (turns out it's not at the moment but I can't verify that) it could be a good replacement for my no longer produced chalk.
oh yeah, you probably want to see it.
