How to use BLOPENS
BLOPENS come with the cartridge in the storage position.
Remove the mouthpiece and cartridge. Turn the cartridge around and Insert as shown, ensuring the tip is pushed fully into the end. Replace the mouthpiece.
Put the tip of the pen about 8-10cm distance away from your paper and blow through the mouthpiece.
To store pens and prevent them from drying out, repeat step 2 turning the cartridge back around.
