"Oil Slick" Pen Blank
This is not your usual rainbow. A 6 color combination of rainbow colors comes together in what looks like an oil slick at just the right angle. Open up some creativity when painting the inside of this blank after drilling... Black will truly get you an oil slick look while white will brighten the colors a bit. This combination is a favorite with other pen makers as well as my pen customers.
Each blank measures 5.25" x 13/16" x 13/16"
