International Standard Fountain Pen Ink Converter, Fit for Jinhao,Baoer, Fuliwen and Most of The Chinese Pen - 5 Pcs Push in Style

These are actually very well made. They are a perfect replacement for the converter that came with the pen that I have. I'll I have to say is to make sure that the pen that you have will accept these.

I changed my Hero 200A fountain pen’s converter into this one, worked perfectly.

Didn't actually fit my Kaweco pens even though it claims they are "standard" size. Didn't bother returning them since they are tiny & cheap to begin with. Ended up just giving them to someone else who thought they had a pen they would work in instead. Oh well, live & learn.

Does not fit my Colobri Fountain, which takes International Standard cartridges. The problem seems to be that his cartridge widens a straight barrel after the tip, whereas the international standard has a slightly narrower part of the barrel after the tip so that the cartridge can fit into the pen.

Initially I received the wrong product, however, the company was quick to fix the problem, and I am now satisfied with my purchase and everything is in order.

These was excellent replacement for original ink converter that came with the pen. It fit the pen perfectly and hold the ink well.

3 out of 5 of these converters worked. Two of them didn’t have the squeegee-like tip attached to the end of the threaded gizmo that draws the ink up. Worthless.Other than that, I got them quickly but still wonder in this day-and-age how crap like this makes it all the way down to the end-user. Does Sipliv have no quality control?Listen up Sipliv, quality control is good and can make you money by making a good name and reputation and getting repeat customers. Because of the shabby converters I got, I'll remember your name to avoid getting disappointed again.Try harder!

I purchased these for a Mont Blanc, Arrow and pelecan pen. They did not fit, although they were listed as standard size. I started to return them and ran out of time so I threw them in the trash. It was a sad waste of $5.
