This is the Candy Craft Chocolate Pen by Skyrocket Toys. It’s a pen that, instead of ink, is filled with chocolate. It's a pen... that writes in delicious chocolate. The $30 pen, available this fall, uses a built-in electric motor to extrude real liquid chocolate from tubes that can be swapped in and out to change colors. So kids can easily create hand-drawn designs, or simply use the pen to precisely fill moulds.
