Set of 5 Tombow Air Press Ballpoint Pens Full with 5 Black Refills and an Original Logo Sticker Oil-Based (BC-AP12), 0.7mm, Black, (BR-SF33)

Air Press BC-AP12 (Black) / Refill BR-SF33 (5-pack) Equipped with APS, compressed air changes the way you write. APS (AirPress System) is a unique mechanism that creates compressed air with each knock to push out ink. It promises reliable writing even in difficult situations such as "speed writing," "writing with your head held high," and "writing on damp paper." This is a knock-type pressurized oil-based ballpoint pen packed with features for active use. Rubber body The body surface is finished with soft resin (elastomer), so it can be held firmly even with wet hands or while wearing gloves. (The transparent shaft is made of acrylic resin.) Strong Clip The strong, flexible wire clip opens wide and can securely hold anything from a single sheet of copy paper to thicker items. Short body The total length is 122 mm, making it suitable for carrying. It is about 20% shorter than a standard office ballpoint pen (around 150 mm), allowing for quick tapping and making it suitable for writing and shorthand in small or crowded places.
