Asvine5 Pack Fountain Pen Ink Syringe Filler, Spring Converter with Removable Blunt Needle Tip

Great value. Works as described.

Excellent.

Design works out mostly well. The tips on occasion do seem easy to knock off. Works better when ink in refill jar gets low.

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.

Had bought these to make refills for my fountain pen easy, but wasn't sure if the needle would fit directly for the one in my pen. Turned out it would, but since I still have 4 backup ones now, I planned on using them for other colors. Since this was my first fountain pen I bought, I learned different size tips alter how often you have to refill, but these are definitely worth the money for easy refills to reach all the way down when almost out of ink.

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.

These work great to get ink from jars!

Work very well
