Marcelo Insua a.k.a Mr. Tango, designed his own "boon" years ago. Through thousands of performances he has finally perfected a boon that won't fall off your finger, and allows you to write more legibly than ever before. Most boon writers have a concave shape that fits onto the fingertip. But this concave shape poses problems as you write or draw in secret, and so Marcelo has developed a new, better way to transcribe information. If you have ever been scared to try a boon writer, this is the product for you! Gimmick and DVD included.
