Yo-Bonic's Yo-Bonic Baby Boy yo-yo. "Lightweight, precision balanced polyproprolene gives you loads of smiles." A pale blue, fixed metal axle yo-yo with a happy face on it. A popular cultural icon from the 1970s, it was also known as Smiley Face. The back of the saddle header card has a Yo-Bonic Baby Birth Announcment that you could cut out, fill in, and frame. Perfect for your newborn baby boy's bedroom. That's Yo-Bonic. The company was based out of Seattle, Washington. Maria Carilao, the president and CE-Yo of Yo-Bonic stills owns the yobonic domain name, despite the 404 website.
