Ink reservoir with cap

Ink reservoir with cap. Brand new. Use this reservoir in the Fountain Pen or the Pump Pen. Carry around with extra ink for a quick change while drawing in the field. 

Note: The product picture shows two reservoirs to give you better views of the product. 

This reservoir also fits into the Kohinoor Art Pen. Two pictures are shown. The Kohinoor Art Pen is a popular artist fountain pen produced thirty years ago, and now found occasionally on eBay. The only problem with that pen is the small reservoir. Our reservoir slides into place, seals perfectly, and triples the carrying capacity of the pen.
