The highly portable, extendable "SL-F1 mini" ballpoint pen is back in a limited edition! With a slide mechanism that extends the barrel, the pen tip appears when extended, allowing for writing. It has a short, slim body that won't take up much space in a small planner, and a high-quality design with a metal barrel and metal clip. It's 107mm when in use and 84mm when stored, making it compact to carry around. Purchased in 2024. Zebra Ballpoint diameter: 0.7mm Size: Total length 84mm/107mm (when extended), maximum diameter φ11.7mm ● Weight: 10.9g ● Ink: Black. Refills include 4C-0.7芯, etc. This one is gray and is new and unused. It's a perfect fit for an M5 planner (depending on the planner). However, it is thin. Please refrain from returns or refunds. Please note that shipping is unavailable from April 15th to 18th. Thank you for your consideration.
