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 blue.
These are from a custom mold made by Lab Fifteen. 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
