Zebra has announced a collaboration model of its customizable multi-function pen, the Prefill, with a four-color holder, in conjunction with photographer Mika Ninagawa's digital photo book "Nina Digi." Ninagawa selected the images to be used from Nina Digi and produced the pen down to the smallest details, including the color scheme of the body parts. It comes in seven vibrant colors, including magenta flower, purple butterfly, and pink rose. It is targeted at women in their teens to 30s who are interested in photography and design. Each pen costs 315 yen, and refills are sold separately. It will be available at stationery stores nationwide from the 10th of next month.
