I purchased 10 of these in Switzerland this summer. Caran d’Ache high-end instruments can be found in the US, but their “office product” line seems limited to Switzerland. This are the nicest cheap pens ever – shaped like classical fountain pens, built to survive a Swiss army bootcamp, showing just enough of the traditional Caran d’Ache hexagonal profile.
Update: I found one US vendor who sells these in packs of 10. Christmas stocking stuffers?
