These aren't your ordinary whistles – they're miniature works of art from the famous Italian design house Alessi, created by designer Michael Graves. This set includes two whistles made from durable polyamide plastic: one is shaped like a cute bird, and the other looks like a fun, prehistoric reptilian bird (kind of a dinosaur vibe). One is red, and the other is light green. They're functional whistles, loud and clear, perfect for referees, coaches, teachers, or for keeping in your emergency kit. But they're also super cool collectible design objects. You could use them in the kitchen to call the family to dinner, or just display them on a shelf. They're conversation starters. Hand wash is recommended for cleaning. A unique and playful gift for design enthusiasts, collectors, or anyone who appreciates a mix of function and fun style.
