Oscilloscope Enamel Pin - Sawtooth Wave Glow-in-the-Dark

The design is inspired by my Tektronix T922 oscilloscope. This o-scope is easily one of my favorite tools for function and also for its style.

The oscilloscope displays a sawtooth wave that glows in the dark to emulate that cool CRT glow.

Size: 1-1/8" high x 1" wide

It comes with one metal butterfly clutch and pinned to a backing card.
