TX Keyboards and I have both, separately reached out to the person in charge of approving these requests but haven't heard back in a while. We'll wait and see if they respond, if not we'll talk to GMK to see if they can get ahold of the person.
In other news, Classic Retro/9009/KA1953 colorway for Shinethrough will be happening at a separate time as a children kit for another set. (Here's a hint, it's obviously going to be GMK Classic Retro something)
