You will be purchasing a GENUINE Jinhao Size 6 (6mm) Fountain Pen feed to fit Jinhao X450, X750, 159, 1200, 650 and a few more models. These are genuine feeds that come out of those modelled pens, not the common 'faded grey' 6mm 'HERO' feed which does not fit these pens correctly.  Sourced directly from Jinhao, quality & compatibility is assured. Washing the feed in hot soapy water before installation ensures flow is optimal. 

Feed circumference: 6mm. This may fit other pen models such as TWSBI, Sailor, Baoer but I cannot guarantee this per model. 

My shop supplies all sorts of pens & spare parts for those pens, as well as Size 6 Custom grinds & Zebra G nibs (to match this feed), and regular Size 6 nibs, check it out!
