Anyone familiar with neo. GYOKKO?

[jzeigler88]

I am curious if anyone has any knowledge theyd be willing to share in regards to neofinetia GYOKKO? I cannot find any sort of information on it at all online, I just know I saw one listed and purchased it as I liked how it looked and it was something new. Anyways, it is a bean leaf that supposedly has tiger striping (at least sometimes it does, possibly the tiger pattern comes and goes depending?)? I bought it from Satomi of Seed-Engei, so I know I should have a decent quality plant. the description said it was a Tamakongo variant, and can have the tiger striping. If anyone can offer any input about this bean leaf type Id appreciate it. Essentially I am just curious if it is a valid/common type, or if it really is just a tomakongo, and if it can have tiger striping, and if so, how/what makes the striping appear?
