About Hello Kitty Hello Sanrio's most popular character, Hello Kitty, is one of the most recognizable faces in the world! She has won over the hearts of younger and older girls (and boys) since Sanrio began producing Hello Kitty themed goods in 1974. Adorning everything from clothing to cookware, she is an incredibly popular figure, leaving her fans no shortage of ways to show off their love of all things Hello Kitty. Now, everyone's favorite kawaii kitty is available in the form of an Otamatone!About the Otamatone An adorable, quirky instrument whose sound has been described as similar to that of a synthesizer or theremin with a playing style resembling that of a string instrument, the Otamatone creates electronic tones that you can control based on the position of your finger on the touch-sensitive fretboard. Use a switch on the back to choose an octave and slide your fingers up and down to play different notes. Open the Otamatone's mouth with a squeeze to change the sound from a hum to an ?ahh? and create a ?Wah Wah? effect. A perfect toy for lovers of all things cute, silly, and weird, the Otamatone also makes a great gag gift and a unique and amusing gift for violinists and other musicians. Size 5? x 14? x 3?
