Info from Manufacturer: The Zydeco Tie is an instrument-quality washboard shaped like a necktie, that clips on over your collar or neckline. It is crafted of 24-gauge brushed stainless steel. The Zydeco Tie evolved from the wooden framed washboard used by traditional American musicians. Today zydeco musicians wear a "frottoir," a stainless steel washboard with shoulder straps. You can wear your Zydeco Tie anywhere; add a little rhythm to your day. It's a portable party! One pair of size large metal thimbles included, FREE!
