## Customer Reviews

### ⭐⭐⭐ Good, but use with caution
*by H***S on July 9, 2025*

I like these, but feel like they could use improvements. Also, they're pretty thick, kind of like holding a marker, which I like, but might be an issue for others.Pros:• Refillable• Lid securely screws on so it won't come uncapped and leak in a bag or pocket• Clear pen body so you can see how much ink is in the pen• Fine needle tip pen• (so far) writes smoothly with no skipping, dryness, or scratching• Piston fill mechanism can be turned until it clicks when full to sort of lock into place to help prevent accidentally ejecting inkCons:• Piston fill mechanism is built into the pen body instead of being an internal mechanism, so, despite the "lock" element, it's still pretty easy to accidentally turn the piston and shoot ink out, especially if you put the pen cap on the back of the pen when writing (due to the muscle memory of unscrewing the pen cap)• (from personal experience) The piston fill not being internal means that if you put the cap on the back and then aren't very careful when removing it (and/or if part of the piston mechanism is cracked or broken), it's very possible to accidentally rip the piston plunger out entirely and spill all of the ink that was in the pen• I haven't tried this, but I suspect the small (fine) needle tip would most likely jam up if using shimmer inks, so the useable inks are probably limited some by thatTldr; I like these pens, would maybe recommend them for people who like the ink variety of fountain pens, but the writing style of fine/very fine rollerball and ballpoint pens. Just be careful if you put the cap on the back when writing.

### ⭐⭐⭐⭐ Water down Acrylic Ink
*by T***I on July 23, 2025*

I bought these for my acrylic ink fine line drawing. If not using regular ink I found it best to add a little water to thin it out. There were no instructions as to how to fill them so I had to google & even then found it difficult. Not expecting them to last that long but served its purpose for what I needed it for.

### ⭐⭐⭐⭐⭐ Great for reducing waste and a nice smooth writing experience!
*by M***B on January 26, 2025*

LIKE:SMOOTH writing!Easy to fill, just put it into the ink (bottle of fountain pen ink, watercolor, etc) and turn the knob to pull it inNib is fine and writes surprisingly well--very smooth writingComfortable to hold to write withGreat for reducing waste--instead of throwing away pens or cartridge refills, this is very sustainableIf there were more stars, these pens would get them all!
