Preferably red but I'm not too picky right now. Will buy or trade for. I have some Sanwa buttons to trade if there's interested and I can get more Sanwa parts quick and cheap.
I've got some Seimitsu skeleton/pearl buttons. Purple, white/clear, blue, also got regular black buttons, and bubble tops in purple, pink, blue, and clear as well.
Let me know if you're interested in any, all 30mm snap in.
