These syringes are exactly what I was looking for cleaning and refilling fountain pens, converters and cartridges. The blunt needles are small enough to store in the syringe for easy transport and storage. If this is why you are buying these it would be an excellent choice for you.
Why use an expensive ink-converter that's going to fail when you can just refill the plastic cartridge already in the pen? I started doing this with Rotring drawing pens because the ink cartridges that they supply have about six drops of ink in them. Now I just fill them up with Higgins fountain-pen India ink and they're good to go. Works for Schaefer calligraphy pens too.
A very good friend on mine is crazy about fountain pens. He appreciates quality pens and is particular about the ink that goes in them. The syringes allow him to refill empty cartridges with his preference of ink. When I last spoke with him he was recharging a cartridge with his favorite green ink. I highly recommend these syringes.
I was making a terrible mess trying to fill my converter before these (funny thing is that I was using UV ink so it was an invisible mess but if SIU shined their lights on my hands they would have pegged me for a pervert or something)
I didn't have any instructions on how to use these to fill the cartridge so I did still make a mess the first time I used them but after I figured out where to stick that needle all was well and I get about a 110% fill (Pilot says that's okay) on the cartridge compared to the 50% I was getting before.
These are perfect for use in cleaning and filling fountain pens, and it is nice to have extras on hand in case the plastic syringe part gets picked up by a cat from the countertop where it was drying and is used as a toy, causing it to be punctured by the cat’s teeth. Not an entirely hypothetical situation, from my personal experience.
Blunt-tipped, work great, as described. Essential tool for refilling ink cartridges from ink bottles made of any fountain pen brand in any color. Each cartridge can then be re-used 5-10 times before it wears out and is discarded. Choose from a much wider variety of ink colors and types using blunt tipped syringes to re-fill cartridges! Bottled ink is also much more affordable than always buying new ink cartidges for one-time use. Blunt-tipped syringes are also helpful in loading an eyedropper converter pen with ink. These syringes are re-useable many times each within the arena of the fountain pen hobby. They’re marked one time use because other than the tips being blunted for use with fountain pens, they’re otherwise the same item as what’s used in health care settings for injections which is most definitely a one-time-use setting. A useful and handy tool!
These were PERFECT for my needs!! Wish I would have discovered these years ago. I've been using fountain pens for decades and went through ink tubes like crazy. I found buying it in a bottle and refilling is much more economical. I can also experiment with more colors than I ever used to because of the ease of filling a cartridge. Thank you!
If you own real fountain pens, then you know what a pain it can be to clean them between ink changes. These syringes help clean inside the ink reservoir, ink channel, and the feed. Clean your pens well so your ink colors aren’t tainted by old ink.
