A beautiful combination of a trademarked blue looking color (made with Conch Aqua pigment from Divine Island) and a pigment made with real copper. After drilling you can use a neutral silver to pain inside the blank if you're using a kit with a thin finished body. This one is pretty opaque so you can probably go without back painting the blank for most kits.
Slim Blanks measure about .6" x 5" and are suitable for slimlines and pretty much any pen around .5" finished diameter. Drilling on the lathe is your best bet to ensure you maximize the diameter.
