Retro 1951's Tornado Dr Gray gift set includes a twist-top rollerball pen and a 1.15mm pencil. Both the pen and the pencil display the skeleton image with the various names of the bones labeled. The quality is evident by the heavy duty metal barrel, and makes for comfortable writing. Each set comes with extra pencil leads and erasers. Pencil and pen refills are also sold separately, ensuring use of both writing utensils for years to come.
