This is a musical instrument that imitates birdsong. You make the sound by twisting and rubbing it. As the name "bird call" suggests, if you use it outdoors, birds might come closer... (though it depends on your skill). I used it in a wind instrument performance, but I haven't had a chance to use it recently, so I'm putting it up for sale. It produces a louder sound than other companies' products. Retail price: 2,200 yen (tax included)
