N.B. Each kit is supplied as the components only and does not include the material / blank. The Clarion features a clear bottom barrel allowing you to see the cartridge or ink pump and ink level. You know at a glance when it is time to refill with ink. The top cap is your opportunity to show off your turning skills. The pen is fitted with highly polished stainless steel German made medium nib with an iridium tip for a great writing experience. The cap posts with threads on both ends. Includes a pump for liquid ink and cartridge for easy ink replacement. Minimum blank length is only 50mm, a great opportunity to use up those precious small off-cuts you have been saving.-bg
