【New, Unused】Jetstream 3-Color Ballpoint Pens - Set of 4 - Pharmaceutical Company Novelty This is a set of 4 new, unused Jetstream 3-color ballpoint pens. They are novelties given to medical professionals by a pharmaceutical company. Novelties with the pharmaceutical company's product name are being discontinued throughout the industry, so I believe these are valuable items. The pattern on the pen features the Lyrica logo. Excerpt from the Mitsubishi Pencil Co., Ltd. UNI product introduction page: Writes smoothly with low writing resistance Equipped with the world's first revolutionary new ink that achieves "addictive, smooth writing." Compared to existing oil-based ballpoint pens, 'JETSTREAM' achieves smooth writing with low writing resistance regardless of writing speed. Equipped with ultra-low friction Jetstream ink Excellent quick-drying properties The newly developed ink easily penetrates the paper and dries very quickly. It reduces the stress of smudging your hand by touching the lines, which is common with conventional oil-based inks. New mechanism prevents ink flow and backflow Equipped with a spring tip & twin ball mechanism. A spring tip is built-in to accommodate the smooth, low-viscosity new ink. By pressing the ballpoint tip, it prevents ink flow (leakage from the pen tip). In addition, the twin ball mechanism also prevents ink backflow (ink flowing against the pen tip direction). Stored at home. Thank you.
