Yellowstone National Park Floater Pen AND Letter Opener

The Yellowstone National Park Floater Pen and Letter Opener set is a vintage collectible featuring a blue ink color and chrome trim. Made of plastic and originating from Denmark ( pen clip photo shows Denmark, letter opener top has something marked, but too small to read). Bear in letter opener floats and bison in pen floats also. Pen opening mechanism works, but ink is “ weak” ( see last photo.) Both appear to be in excellent condition, no visible marks or scratches. I have other National park floater pens listed and would combine shipping.
