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

I got this as a replacement for my Ferris Wheel Press Bijou pen. This is an easy to use converter and was ready to go right after opening. It fit nicely in my Bijou pen and has been working well ever since I got it about 10 days ago. My only complaint is that the ink converter doesn't always flow consistently compared to the one I had before probably because there's no spring or ball inside the cartridge to help flow along. But I'm still giving it 5 stars because the flow only stops after not using the pen for a bit and quickly starts again.

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.

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

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.

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).

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

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.

I primarily use custom-made kitless fountain pens, and most of the ones the pen turners make near exclusively come with K5s, so I like to keep a backup supply on hand in case of disaster. These also fit perfectly with my BENU pens (which are my most used pens after my customs). They hold a good amount of ink and are easy to use. Best part: they can disassemble, so if ink ever sneaks up into the piston mechanism, I can easily take the converter apart and give everything a good clean.

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.

Fast delivery.. Fit in my muji perfectly.. Thx seller

Bought it for my Pelikan Twist pen. Functioning is perfect. It's a little loose in the socket, but that's because Pelikan's "standard" refill size is a little wider than what other brands use. Still, perfectly usable.

Excellent quality. Clean fountain pen prior to adding converter. Fill converter and firmly push in with a slight rotating motion of the converter. It takes quite a bit of force. Very pleased with the German workmanship.
