Custom cast buttons for the Game Boy Color
These are glow in the dark buttons.
By day they are a very light greenish white, with a bit of UV light and they glow bright green.
These are what have been used in my Glow boy build
These are my own molds made by me. The great thing about these is that it has a fully functioning Dpad unlike the ones that currently sold out in china and other retailers that do not hit the diagonals or "feel" different
Sold in sets of A & B plus a Dpad
These are tinted white clear resin which contains GITD powder
