Keystone was one of many names used by Kahn Manufacturing for its 1930s third tier pens. This early 1930s pen capped length is only 3 3/4” from base to ringtop. It is in almost unused condition, in red celluloid with grey pearlescent chunks in the celluloid. The chrome, including the ringtop, is all in excellent condition. The ringtop is secure, and would look equally nice hanging from gold or satin. Its tiny gold nib writes a surprisingly wet, full medium line. The matching pencil, which is of standard length, works well with 0.9mm lead. Its trim is equally clean.
