Keith Haring Vintage Pen Sets (2 sets) Art Merchandising & Media AG Pop Shop

Description

2 Keith Haring Pen Sets in original Aluminum Case Tins with all tags. Bought at the NYC Pop Shop in late 1990s/ early 2000s before it closed.
Each case comes with two pens (one a roller and one a plume)--have never been used so not sure as to working condition (only opened to take these images).
Bottom of each tin lists "Art Merchandising & Media AG" As the Makers.
