The World's Smallest Harmonica is only 4cm long, but it's big on real harmonica sound!

Your teeny-weeny instrument is completely playable and packs a full eight-note C-Major scale into it's tiny metal frame!

Featuring a small keychain clip for attaching to your keys, you can play tons of sweet songs on the go!

What a handy widget to have on hand for spontaneous jam sessions, or whenever you feel the need for a happy tune!

The blow notes are C, E, G and C, and the Draw notes are D, E, A and B.

Available in black, orange and silver (chosen at random).

Recommended for ages 8 and up.
