Brand: Eagle Pencil Co.
Made in: USA
A nearly identical pencil can be found bearing the name Radiolite 91 ... looks like another name change!
The company was originally founded in New York City by the Berolzheimer family, and in 1969 became part of Berol Corporation. Berol was purchased by Empire in 1986, which was purchased by Sanford in 1995 (which is today a division of Newell Brands).
