The most popular and most desirable pen in the Rotring 400 line is the Rotring 400 “Double Push” mechanical pencil. This pencil, and it’s close cousin the Metallic Tikky Double Push, are prized for their interesting 1990s design and push button mechanism. This is what we today call a “double-knock” design.
The Rotring 400 pencil was sold in gunmetal grey and a lighter matte silver. Both are rare today. The pencil was also sold in a set alongside the Rotring 400 ballpoint pen.
The modern version of this pencil is the plastic Rotring Tikky 3-in-1.
The Rotring 400 closely resembles the Rotring Espirit line, which can often confused sellers and collectors. The Rotring 400 ballpoint and mechanical pencil are both extremely similar to the Metallic Tikky, which makes buying the right one online very difficult.
