Review: My favorite pen - I was really suprised by this pen and figured I was throwing my money away when buying it but I was totally wrong. I bought another click-top cheap fountain pen but it had a plastic cap that still needed to be put on otherwise it would dry out and/or leak. This pen doesn't need a cap and fully retracts into the pen. It has a nice weight to it. Despite being plastic it is significantly weightier and sturdier then my other cheap fountain pen. The construction of it feels nice and the click-top is nice, not to light or firm. I like the fine tip and it writes really cleanly. I have no issues with leaking or smears and the ink doesn't bleed on cheap paper. My other fountain pens have a habit of leaking so I am really pleased not to have ink-stained fingers. I did have trouble getting the ink flowing at first and had to squeeze the ink cartage once I had it put in to get it started then put the top half back on. Since then it's worked great. I had it dry out because I forgot to click it and retract the nib so I had to redo the trick of squeezing the cartridge to get it flowing again, but that was totally user error. It was left open for over an hour, it isn't drying out if I leave it open for minutes at a time. I like the grip, I find it comfortable to write with. I just wish it came with black ink instead of blue. I am going to buy their black ink when I am done with this cartridge.
Review: Impressive capless retractable fountain pen - The K016 was an amazing surprise for me. Being a fan of retractable fountain pens, I ordered this pen with little expectation, especially at this price point. This has got to be one of the best values in the fountain pen world. Being aimed at the student market, it’s plastic. The plastic is dense and sturdy. It does not look or feel cheap, however. The knock action isn’t silent but it’s relatively smooth. The way this pen seals is quite innovative. The opening on the section has a rubbery circular membrane with a slit. The nib emerges through the slit and retracts back inside. The seal is very effective and the nib hasn’t run dry. This pen has written first stroke, every stroke. This pen is ready to jump into action with a fast click, and off you go, with a smooth nib, for quick notes or long writing sessions in comfort. Four ink cartridges of ink are included, and one empty. The empty cartridge is for filling with your choice of bottled ink, or ink sample vials. Easiest way to fill is with a syringe or pipete. They are very sturdy and will refill many times. You cannot use a converter. Simply fill their cartridge with a blunt syringe. Reverse writing works very well. It’s a light pen, weighing 14g inked. Highly recommended and lots of fun. I’ll be gettIng more colors.

### ⭐⭐⭐⭐⭐ Great value, Great Pen
*by R***I on July 17, 2025*

If you like a fountain pen but are looking for something more contemporary, this is your pen. It was no problem to insert the ink cartridge and once it was in, I pushed the top button and a fountain pen nib came out, and it was easy to use. Looks like a regular pen with a longer button on the end to extend the point. I would recommend it to anyone that appreciates a fountain pen. The value was great for the price paid. The pen seems to be well constructed and will last long. The nib goes into a holder and did not leak any ink out when closed, so I wouldn't hesitate to carry it in a shirt pocket. The nib is a fine point and wrote smoothly.
