Hand-assembled lo-fi microphone made from a solid steel beer can from the 1970's; extremely limited supply since they don't stamp these cans any longer.
Naturally capture recordings and perform live without the need for effects to get that vintage sound.
Mic stand attachment has been added to the can for you to easily screw the can directly onto the mic stand itself.
1/4 inch output jack might be on the top or bottom of the can and allows for connection to mixers, amps, pedalboards, and more.
The placement of the 1/4 inch output is dependent on which side of the can was punctured to drain these 50+ years ago and may differ from what's pictured (though what is pictured is the most in-stock 1/4 inch orientation).
