Schmidt K5 Push In Deluxe Fountain Pen Ink Converter (Pack of 2)

Have had issues with other brands. These work and perform flawlessly. Operation is smooth in both directions. I have ordered several for use in multiple pens and for spares. (Also have the #6 (screw in, for pens that use them)) no problems). A visible silver coil inside the ink chamber of others is a warning flag. That coil inhibits complete emptying of the ink (for cleaning) and reduces the amount of ink that can be drawn in. The only thing I can see that it DOES do, ( based on the examination of a converter that was received defective ) it prevents the shaft from dropping out of knob when the plunger reaches the nozzle which would make it impossible fill the tank (bad design/engineering).

The original converter for my Wordsworth pen finally gave up the ghost. I'm currently using a cartridge and when it's empty I'll try the Schmidt K5 converter of this review. It appears to be well made. Eye balling the lineup, I think it will fit okay. We shall see.

These work just as advertsed

I purchased these converter to replace one in a Wordsworth & Black pen. I saw other reviewers mention that the fit was tight to very tight. Mine was tight to the point of not being able to press any harder. I was ready to give up and lose the cost of the converters as well as the use of the W&B pen. In desperation I decided to try installing it on a Jinhao pen, which always felt like it had a "robust" build quality and maybe a looser fit. It took a hard press but it connected. Then, I took the converter that had been on the Jinhao, (and hopefully broken-in a bit) and it too went on after a very firm push. Once everything was assembled, the converters worked perfectly. I will grade them 4-stars because they work well and don't leak. I'll hold one star back due to the extra effort needed though I can't really blame them for the fit issue. Hope this helps someone in the future.

I wanted a Schmidt K5 converter to be able to enjoy a wide variety of bottled inks on my vintage Diabolo de Cartier fountain pen. The converter fits perfectly and works accordingly. I even have an extra converter in case I need it and the price for the two-pack was very attractive too. I am very happy with my purchase.

Schmidt cartridge converters are produced for many pen manufacturers, and are provided with your new pen as Original Equipment Manufactured (OEM) parts/accessories. If your fountain pens takes Standard International Short Cartridges, and has room in the body for two cartridges, this cartridge converter will fit, and work flawlessly, in your fountain pen. Some manufacturers (Lamy, Pilot, Platinum, Sailor) have their own proprietary ink cartridges and converters. If your pen does NOT take Standard International Short Cartridges, AND/OR doesn't have room for two cartridges in the body of the pen, this cartridge converter will NOT work in your pen.

product was as described, and arrived in a timely fashion.

Fits all my fountain pens and keeps a lost art alive. Good for and quality

Works as expected

Perfect fit for Amazon basics pen. Never liked cartridges. This converter will give me more freedom to choose the ink color that I want. Fill it up and it will hold slightly more ink than the cartridge the pen came with. This is a screw type converter and not a plunger which I am not a fan of. One converter cost almost as much as the pen though, even when you buy them as a pair. Also remember this is just an ink container. Just by getting one of these, if you are looking to find a magical improvement in your pen, then this is not what you would want to buy. The performance of the pen depends on the nib quality, the ink delivery from the nib, the quality of the ink, the paper you are using and of course the way you write. Definitely satisfied.
