SimplePen was born from a simple concept, to create the MOST simple pen in existence. 

After a number of failed iterations we conceptualized a pen that could be used in its raw form, turning the cartridge itself into the body of the pen. With this in mind we selected the Space Pen as our prime candidate due to its light yet comfortable housing as well as its pressurized leak proof system.

Features:

• Ultralight design is great for backpacking or EDC
• Space Pen insert prevents ink explosions
• Easily customizable with logos or remixed to fit alternative cartridges
• Quick print that can be done with end of roll filament
• Eco friendly due to small amount of waste and reusability
• Uniquely simple

Notes:

• Designed to have a snug fit so may need minor scaling or sanding for your setup/filament
• Ensure inner surface is smooth as defects may dent insert when pressure fit
