Description The TWSBI Pipe Filler is a stainless steel pipe created as an extension to reach all the way down into the corner of almost empty ink bottles to help people fill their pens. This is especially handy for small or short bottles, or when you run low on ink. It fits standard international converter openings and the TWSBI Diamond series fountain pen barrels. We offer Free Shipping on all orders over $59 for US customers, and for orders over $250 for our Canadian customers.
