Kaweco Dia 2 Ballpen is another Kaweco classic originating from the 1930's, brought up to date with modern production methods to exacting standards. The distinctive kurling on cap and barrel gives the glossy black Dia a unique design element. The barrel is made from high-quality injection-moulded acrylic, supported by CNC-milled aluminium parts where strength and long life are essential. The clip is solid brass for strength and flexibility. The Kaweco logo in metal is present on the end of the cap. The Dia feels much more of a substantial weight in the hand than many comparable 'plastic' pens. Twist-action retractable design, supplied with medium blue refill. 140mm long and 30g in weight.
