Thank you for viewing. These are all Jetstream ballpoint pens. I purchased them and stored them together in a pen stand. Because they were stored together, there may be some scratches that are difficult to see. * The unused 4-color pens with a pink body are 0.7mm, and the 4-color pens with a navy blue body are 0.5mm. * The 3 black-bodied pens are unused and have 0.5mm ink. * The 3 transparent-bodied pens have 0.38mm ink, and I used the blue ink a little. * The 2 beige-bodied pens have not been used since purchase. * The single-color pink pen is 0.7mm and has not been used. * The ink size of the pens with company names is unknown. As a bonus, I will include a Jetstream 0.7mm black ink refill. Please purchase these items with the understanding that they are used. Please refrain from purchasing individual items or negotiating a price reduction.
