Question about building a Midi Fighter

Question about building a Midi Fighter

I just recently saw these and have been really wanting to buy one, and I have seen other colored buttons like the green colored arcade buttons but when I am building one in the store there isnt an option for green buttons. Are they just no longer available or out of stock? Sorry if this isnt the right forum just figured it would make sense to post here questioning it

Hey - Green buttons are out of stock they should be back in stock within 2 weeks.
