Refill Fountain Pen Ink Cartridges with a Blunt Tip Needle Bottle

If you own a fountain pen that has a cartridge filling system, you can easily refill your empty ink cartridges or ink converter using a blunt tip needle bottle.

  1. Put some ink into the needle bottle – a small funnel can be used to make this easier.
  2. If you are changing ink colors it would be a good idea to clean your fountain pen and rinse out your empty cartridge with water first. A blunt tip needle bottle filled with clean water is a good way to rinse out ink cartridges. You may want to let the cleaned pen and ink cartridge dry overnight before you refill them.
  3. Insert the blunt tip needle through the small opening on the end of the cartridge down towards the bottom of your empty cartridge. This way as you fill the cartridge the air will naturally come out the top and not form too many ink bubbles.
  4. Gently squeeze the needle bottle and fill the cartridge or converter not quite to the top with ink.
  5. Put the refilled ink cartridge into your fountain pen and you’re finished!

I’ve heard that some people use a dab of glue from a hot glue gun to reseal the cartridges so they can take extra ink cartridges with them. If you decide to give this a try, be aware that it’s not foolproof. You may want to carry the ink cartridges in a plastic zip top bag to prevent any accidents.

There are many advantages to using a blunt tip needle bottle to refill your empty fountain pen ink cartridges:

  • Bottled ink is much cheaper to use than ink that comes in cartridges.
  • Since the empty cartridges can be re-used many times before discarding them, there is less plastic waste going into the environment.
  • Ink cartridges usually can hold more ink than a comparable ink converter.
  • The needle tip bottle can hold lots of ink and it doesn’t need to be cleaned after each use like a syringe does.
  • The blunt tip needle is safer to use for refilling than a sharp tip syringe.
  • The plunger on a syringe can be hard to control leading to small ink explosions, but the bottle yields to very gentle pressure.
  • You can fill the needle bottle with your own custom ink color and use it to create your own custom cartridges.
  • You can fill cartridges with ink that isn’t available in cartridges such as Noodler’s and Pilot Iroshizuku.

The little wire in the cap of the blunt tip needle bottle isn’t completely necessary, but it does serve a couple of useful purposes. Since the wire goes into the needle when the bottle is capped it helps to prevent any clogs and it also helps to prevent leaks if the bottle tips over. If the little wire in the cap comes out, you can gently push it back in.

Do you ever refill empty fountain pen ink cartridges? What method do you use? Do you have any tips that you’d like to pass along?

This is a really neat trick! I use mostly a syringe to refill cartridges :)

Pretty cool...

Where may one obtain these bottles? Art store or such?

We have them at Writer's Bloc if you want to give one a try: http://www.shopwritersbloc.com/bltipnebofor.html

I use drawing up needles and syringes (from medical supplies shops - 100 needles for about £8 and 100 syringes for £10-15 (depending upon capacity of the syringe))

Cheap enough to change syringe/needle between inks to avoid contamination - also great for mixing - if you buy graduated 1ml syringes you can measure your ink for mixes very accurately.

Needle bottles are brilliant, but I would fill with one colour and use only for that. For UK folks TWD also do a bottle/needle and syringe/needle filling kits.
