This is an extremely rare Roller Ball pen from ACME. This is a tooling test for not only a brand new shape for a collection to be named ATP (Aluminum Tube Pen), but also anodized color into the aluminum body of the pen. On top of that, we also experimented with different etching patterns. This pen is a blue gloss finish and has vertical and horizontal lines around the cylinder of the pen. These prototypes are extremely rare, only a few will be for sale. After they're sold, no more will ever be available.
