Binary is a two color mix with a pearl white and onyx black. This is an excellent choice for black plated kits. The diamond really sparkles in the black and adds depth to the white.
These are best drilled on the lathe and work great for Jr. sized pens and smaller. For best results paint the inside of the blank after drilling. (White paint is best for this color combination.)
