LAMY is a world-famous pen company headquartered in Germany. 

A variety of ink cartridges or a LAMY converter can be used with this pen. Installing ink cartridges is easy—simply insert the cartridge into the pen nib section (no need to push the cartridge all the way in), then twist the pen barrel onto the nib section. Attaching the barrel automatically punctures and installs the ink cartridge.

This pen includes one blue LAMY T10 cartridge.
