Place the wider end in your mouth and hum "oo, oo" to make a sound. A spare membrane is included.

I will take the item directly to the post office, have them apply a dated stamp, and take a photo of it to prevent shipping errors or omissions). The item will be wrapped in bubble wrap and sent in an envelope. Other colors are also available. We kindly ask that you refrain from negotiating discounts on this item if purchased individually. Even if the item sells out while you have it "liked," I will immediately relist it under the same title if I still have it in stock, so please search for it again.
