N.B. Each kit is supplied as the components only and does not include the material / blank. Choose from two very popular classic writing instruments, one in satin gold and the other in a nickel satin finish, both use a standard twist mechanism. If a mandrel is used to make these pens no bushings are necessary and a 7mm drill will be required. We recommend the Fisch pen drill (502103) which is available in this size. For ink refills order 310492.
