LanxiviJinhao Metal Fountain Pen Ink Converter, Pack of 10, Fit for Jinhao,Baoer, Fuliwen Pen,Duke and 95% Chinese Pen

So Fast delivery And Nice product quality

These converters are a good deal for their cost, and they fit Jinhao pens perfectly. They will fit other standard international pens, though the seal is not always perfect, depending on the pen. The plastic may be a little brittle; I had one crack during cleaning after a few months of use. But for the most part, they're about what you'd expect this type of converter.

I use the converter for different brand/ types of fountain pens. They fit in most (not in LAMY). Your cartridge holding part of the pen has to have at least a diameter of 8 mm. The cartridge part (clear) is the same size as a regular ink cartridge. The part that pulls the ink in (black) is connected with a golden sleeve to the cartridge. This sleeve makes the converter 2 mm thicker than a regular ink cartridge.I inserted the converter into the fountain pen the same way as an ink cartridge. For some pens, I had to wriggle a bit to get it properly connected. Accidentally I loosened the golden sleeve on one carriage and the whole converter separated into parts. There was no problem to assemble it back.I have the converter only a few days. So far there is no leaking or spilling. I can refill the converter outside the pen, or I also pulled the ink through the tip of the pen. Both ways work fine. I will use the second way in the future, since I don't want to provoke spillage through damaging the clear plastic front part.

These are dependable but cost 1/10th the price of some other brands. They fit most any fountain pen that takes standard international ink cartridges. They won't fit proprietary sizes like Cross, Parker, Pilot, Sheaffer, etc., but they should fit Lamy, Pelikan, Waterman, Faber Castell, Rotring, and any Chinese brand. In my experience, maybe 1 in 20 will be faulty in that you can't draw ink into the cartridge the very first time you use it. But I have yet to have one of the ones that do work fail on me. And, since they fit inside your pen, nobody will see it so they won't know that your expensive German-made Rotring pen has a cheap Chinese ink converter. Recommended.

A "Gradual Plunge" is impossible! Therefore, no matter how gentle the press, ink will spirt.Forwarned with this, plunging is performed ONLY above absorbent, disposable material.

You can draw up ink from a bottle and use these in fountain pens. They can be reused too.

These reservoirs really do the job. I love them

The opening doesn’t fit or seal in the pen. Not sized as advertised. Total garbage scram offering by Amazon.
