(M-8-B)  This is a miniature version of the Shure 55 SH Unidyne Unidirectional Dynamic Microphone in jewelry tac pin form (NOT a working mike, this is jewelry ONLY). You'll see the real mike on MTV and old film newsreels. Cast in pewter with bright nickel-silver plate (non-tarnish), three dimensional, 1 1/8" long (any gold showing is only a reflection, please disregard; the mic is silver). DETAIL CANNOT BE FAULTED, EVEN BY PROFESSIONALS. Great for guy or gal!
