This is a set of two Jetstream pens and three refills. All are 0.5mm. [Pens] * Black ink pen x 1 * Tri-color pen (black, red, blue ink) ... No black ink. Blue ink is almost empty. [0.5mm Refills] * Red x 1 * Blue x 2 * The black ink pen was purchased in February of this year and used 2-3 times. * I liked the tri-color pen and used it often, but it's still usable. Since the black ink is gone, please prepare a "Jetstream refill ink 10% more" separately. Please check the condition in the images.
