Recycled Cassette Neckties. These thin ties are made from recorded audio cassette tape blended with colored thread. If you run a tape head over it, there is actually audible sound. We're all about recycling, especially when it looks really good with a smart suit and has a fun secret use. Just think how solid an opener that would be: when a girl compliments you, then explain that your necktie plays music. If that doesn't seal the deal, well then we don't know what would.
