saiyuuki company

It has taken a long time for me to finally make the connection between the MR mark and Saiyuuki, as not all pieces bear it. I believe it may be the signature of a particular artist in the company, but am not certain. Thanks to a seller on Yahoo Japan (and Celga.com), I recently found a piece that not only bore the mark, but the Saiyuuki sticker (the first kanji in their name) as well! This company often has very detailed product boxes, featuring an illustration of the neko inside. Some manufacturing may be done in China.
