Vintage Science Ruler
Authentic Mad Scientist Ruler.
Never used ruler from the FLUO-X-SPEC Laboratory on 718 Sherman Street, Denver, Colorado 80203.
Perfect partner for your mad scientist pencil. We found a few of these in the back of the extremely heavy file cabinets we bought from the estate. There is no telling what sort of dynamic energies are surrounding this white plastic ruler.
Pictured is a snapshot of the original FLUO-X-SPEC lab techs left behind with the pencils and rulers. We dont really know who they are, but it is pretty clear that they are some mad scientists indeed.
