Toner Cartrages

Can you remember the time that you did not have a printer at home? They are incredibly useful and the printer is usually not that expensive. Sadly, ink is another story, and they can be pricey, especially ink jet cartridges.

There are many available methods for refilling fountain pens. In the USA, many patents were already issued to different companies like Button, Click, Lever, Matchstick and also the coin methods. All these methods have used a system where a little pressure is applied to the sac or internal plate to allow the ink to go in and out.
