Quick start note:
Zenzoi™ Fountain Pens are crafted to accept either a disposable ink cartridge or an ink converter (usually included inside the pen's barril)
Ink Cartridge Installation
Zenzoi™ Fountain Pens use an international standard size cartridge. Premium Zenzoi™ Fountain Pens have Schmidt Nibs and they need special international standard size cartridge. (See Below)
- Remove the pen’s cap
- Unscrew the pen’s barrel (grip section)
- Remove the empty converter (If still inside)
- Insert the ink cartridges in the nip section of the pen (see below)
- Screw the pen’s barrel (grip section)
- Allow the ink to flow to the nip tip.
Please remember to wait few minutes and shake your new pen downwards few times dynamically after inserting the very first ink cartridge to jump start the ink flow.
It's done correctly you should see first drops of ink come out through the pen's nib (which will get the nib initially a bit moist). For Premium pens there is no need of shaking the pen. Best if you do this process above a piece of paper or above the kitchen sink to not stain your surroundings.
The use of the converter require a more detail explanation (see video below about ink converter refill) (There is one empty inside Zenzoi™ fountain pens)
Using your pen
- Fountain pens are design to be held at 45% angle.
- Don’t press too hard, relax your grip when using your pen
- Protec the pen’s nip by keeping the cap on when no using it
- Ink dries, so wash the pen with water regularly or when necessary
- Don’t write on rough surfaces
Ink cartridges vs converts
Fountain pen users have the convenience of choosing between two filling options. Cartridges are easier and less prone to creating a mess while converters are more cost effective and provide a sense of nostalgia for old-fashioned pen users.
- Converters, if cleaned often after filling of the ink, can be reused for many years and do not need to be replaced often.
- Disposable ink cartridges have to be replaced more often (less ink fits the cartridge than the converter) and are less cost effective than a bottle of good ink. (Zenzoi™ fountain pens use international standard size 1.5” or 3.8 cm).
Pros: Fountain pen users have the luxury and convenience of choosing between two filling options. Cartridges are easier and less prone to creating a mess while converters are more cost effective and provide a sense of nostalgia for old-fashioned pen users.
Cons: Disposable ink cartridges have to be replaced more often and are less cost effective than a bottle of good ink. Filling using a converter can be messy for the novice fountain pen user and may require more cleaning or maintenance.
Common types of fountain pen cartridges
International Size Ink Cartridge Refill
Although International Standard Size Cartridges have the same size (1.5" or 3.81cm), the suction part of the cartridge can vary on length. Zenzoi™ Premium Fountain Pens can only use 2.3mm German made nibs. This type of cartridges can also be use in all other Zenzoi™ Fountian Pens
IMPORTANT TIP: When buying ink cartridges for your ZenZoi™ pen please get cartridges shown above and stay away from branded ones as they often fit only one particular brand that sells them (typical practice of some brands to lock users with their brand).
You should be able to easily recognize these proprietary cartridges as their shape or size does not meet international standard, is odd and fits just one brand selling them. Some examples are below.

Ink Converter Refill Process
Another option for refilling your pen is bottled ink. You would use the converter included inside your pen to draw ink directly from any ink bottle of your choice.
The most commonly used types of inside converters are piston and squeeze types.
The one we use with our pens is piston type (as we find it more precise and not causing air bubbles) which is included inside the barrel of every ZenZoi™ fountain pen.
This youtube link below shows how to refill piston type of converters by placing the nib inside the ink bottle and twisting the converter:
