The first six we sell include a foam ball mic cover (white)

Inconspicuous, matte black, omnidirectional miniature microphone. 3.5.m (I 1-ft. 8.-in.) connecting cord. Lapel or buttonhole microphone For voice pickup. Its wide frequency range makes it a very good instrument microphone, too. May be installed inside a guitar sound hole; also suited for violin and zither. To mic up a grand piano, tape two C 567's to the lid, which may then be closed For higher gain-before-feedback.
