Game Boy Advance - Custom Buttons - Cool Opal
Custom-cast buttons for the Game Boy Advance.
My buttons are hand-cast in my own molds, and feature a fully-functioning d-pad - unlike the ones from China and other retailers which do not hit the diagonals well and feel odd.
First a clear resin is poured and allowed to cure, Then a second pour is made that contains a iridescent foil produce the Opal effects you see in the images
The Cool iridescent foil produces 3 colours, green and magenta depending on the way the light shines on them. These are highly reflective but also semi transparent.
