Both 4-packs of pens included in this bundle consist of 0.5mm fine needle point gel pens - one in black ink, and the other in blue ink. All pens are push-button retractable and include clips. This means they are convenient to store in a shirt pocket, handbag, briefcase or backpack, and ink will not stain. These high-quality gel pens receive great reviews for a reason, like "best gel pen I've ever used."
