Handcrafted in Cheshire at the Sigma Workshop. This is the Sigma Classic Fountain Pen . The pens are handturned from Italian acrylic and polished to perfection. The nib is a German 18kt. gold-plated medium stroke and we can offer an upgrade to 18kt. solid gold in Fine or Medium. This is a good quality pen and it performs to the standard expected of all Sigma writing instruments. The pen is fitted with a convertor/filler as standard but it also accepts universal cartridges. Presentation is in a velvet-lined case for the standard versions and a Red leatherette finish case with satin lining for the gold nib version. Full Sigma Warranty.
