Plastic barrel, plastic clip pen. Banner pens are designed to hold a full color retractable advertising banner, which greatly increases the promotional value of a pen. When the banner is fully retracted, an area of 2 cm x 6.8 cm at the end of the banner will show through the clear barrel. Arranging a logo or message on this space allows you to take advantage of the high quality 4-color process print area. Ink colors: black, blue, red. Bulk packing in poly bag.
