Asvine Hongdian Fountain Pen Ink Converter, Pack of 5, Bore Diameter 3.4mm

Uso la mia Black Forest Max con inchiostri di diverso colore e preferisco dedicare un converter ad ognuno di questi piuttosto che dover pulire lo stesso a fondo in occasione di ogni cambio. Converter di buona qualità. Molto soddisfatto!

Good converter and quick delivery.

Only used one so far but it works just fine so I expect the rest in the packet to be the same. Much better than using disposable cartridges and I love the pen, so, pretty happy to be able to get the reusable cartridges easily.

Identical dimensions to the converter that came with my 1980s Parker Duofold, which was leaking and had a problem with ink flow. It also fits in a Parker 45. It does NOT fit in a Parker 88/Rialto, which is very slim and came with a slightly narrower 70s style bladder converter. Note that this Hongdian converter has a small stainless steel spring which breaks the ink surface tension, to prevent a flow problem I experienced in my Duofold, where it quit working after a page or two of writing and I had to twist the converter down to get it working again. I can confirm, after writing around ten pages, that the converter has fixed the flow problem in my Duofold pen. Anyway, 5 converters for the price of 1 Parker converter and it has a spring to help with flow. A very good deal.

Perfect
