Teal Octopus Ink PenThis sweet little octopus will brighten any writing task! I made this pyrex glass pen in my Colorado studio. FREE gift wrap included. The pen itself is made of clear glass. On the end is a hand sculpted aqua octopus. The pen writes in black ink, and is 6 inches long and 9mm wide. The pen can easily be refilled to either change the color of the ink or to replace it when it runs out.
