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

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

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!

The syringes are detachable and sometimes fall off, but otherwise they work fine. I like the spring-loaded aspect and it helps me to not get as much ink on my fingers.

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.

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.

Was really disappointed to see this fit absolutely ZERO of my pens as a standard convertor. If you use Lamy, Cross, Parker, Kaweco, or Rotring pens, there's a good chance you're outta luck in terms of using this as a convertor. And, since you can't use this as a convertor... mostly... ink capacity is just about as useless a measure as the Potrzebie. The design is fine, but cheaply made; expect that little red cap at the top of the spring to just fly off, rendering at least one of your syringes useless. It's a cheap Chinese tube. If you expect it to be some luxurious feeling item, you're a fool. Would I buy again? Probably not. But if you refill cartridges yourself, I can see the value proposition.

perfect

These little mini-syringes make it very easy to extract ink from a cartridge and refill, no converter required. And no mess dipping the head of pen into ink bottle. Not useful for piston fill pens, of course, but if you use cartridge fill fountain pens, this is highly recommended.

Quick delivery and does the job just like i hoped. It helps pulling out the ink from the bottom of my bottles. Can easily recommend!

Nie można połączyć igły z tłoczkiem ponieważ plastikowy łącznik nie pasuje do igły i tłoczka

Muy práctico para rellenar cartuchos de tinta

簡単にボトルインクをカートリッジに入れられるので便利。強いて挙げれば、２パーツを合体して使うが、外れたり使い方次第では押し出しのバネが飛んで使用不可となった。安いので満足はしている

The fittings are *very* tight, I was starting to think maybe the product was defective when I couldn't get the converter piece to go in the cartridge, and then with a little extra force it suddenly snapped in. It was also a bit tight fitting a cartridge into my fountain pen, (to the point I briefly thought it was the wrong size), but a little extra force and it went in snugly. Between that and the fact that I had difficulty drawing the full amount into a cartridge with a single pull of the spring-loaded syringe; I recommend using the method of drawing ink from the bottle with a cartridge fitted with the metal tip, and then filling a cartridge you intend to use from that one. Pulling ink into a syringe, and then removing the tip/converter may sound like a good idea in your head, but is likely a recipe for getting ink everywhere. And definitely practice the first couple times over a surface you don't mind spilling a little ink on, just in case.
