Year after year, our Slimline pens are our top selling writing instruments. Their sleek, refined design makes them an exceptionally popular gift that never goes out of style. We recommend Slimline pen kits for turners who are just starting out because the techniques and skills learned to create them can be easily transferred to other turning projects. Slimline twist pen kits have locking refill mechanisms that accept Cross style refills. Our 24kt gold uses a "premium rack plating" process and is covered with an epoxy coating for extreme durability. Bushings: 12PKBUSH3 Drill Bit: 12-PK-7MM Blank Size: ½” X 4 ¼” Tubes: 12-PKTUBE7
