Asvine 5 Pack Fountain Pen Ink Syringe Filler, Spring Converter with Removable Blunt Needle Tip

These little guys hold a good amount of ink and work like a charm, so much easier to use than a regular syringe. I can now refill my pens with one hand. I'll be purchasing these again, for sure.

Works flawlessly when you know what you're doing. Be careful to not put the needle too far into the reservoir if you're choosing to refill the ink reservoir inside the pen due to it being hard to avoid overflow. But it's fast and easy to use. Definitely recommend!

These have been pretty cool.

These have been great and very simple/efficient to use. Save money by using these instead of disposable cartridges.

Perfect for refilling fountain pen ink cartridges. Easy to clean.

It works

Wish it came with instructions although it’s fairly intuitive, would be nice to have a confirmation other than the photos on Amazon. How it performed well.
