"Roses" Roller Ball Pen, a design by Charles Rennie Mackintosh, comes from ACME Studio's Standard Roller Ball Pens.  Artist's signature is engraved on the cap band and "ACME" is on the clip. The pen is presented in an ACME metal box with a black sleeve and ACME literature.

The ACME Studios was founded by Adrian Olabuenaga and his wife Lesley Bailey in 1985. The company has collaborated with well know artists, musicians and architects producing lines of pens, and art.
