I don't know if it's copied from you litster.

if so that makes me feel bad.
A friend of mine who loves keyboards a lot in China asked me whether I'm interested in the Korean Custom Acrylic cases few days ago, and he can ask MKC to make some. He got a design drawing of the Korean crylic case from probably some Korean guys and send it to MKC.
We three people (including another crazy keyboardlover who also comes to GH) were about to ask MKC to make 3 clear cases just for us. And then I think probably yesterday MKC was bringing this clear acrylic case to the market. He contacted me later last night asking about my interest doing the group buys for the case.
MKC said he took a look on the Korean design drawing, but it turned out it can't be used at all. Because the cover is kinda too high. And it's smaller than our regular 87 tenkeyless keyboards. It also includes 13 screws.
Finally MKC designed a new clear case as shown in my group buy. I really don't wanna make the people who originally designed the acrylic case feel uncomfortable. Just trying to explain a bit more on this.
