【Product Overview】 This is a limited edition earth-tone model of Zebra's long-selling retractable ballpoint pen, the "SL-F1 mini." It features a slide mechanism that extends the pen tip when the barrel is extended. When stored, it's only 8.4cm long, about the size of a lip balm, and fits neatly into mini 5-hole planners, pockets, and pouches. The metal barrel gives it a high-quality feel, and it adds a touch of sophistication to the act of writing, whether for business or everyday use. 【Specifications】 Model Number: BA55-EC Green Size: Total length 84mm (107mm when extended) / Maximum diameter 11.7mm Weight: 10.9g Ink Cartridge: 0.7mm (Oil-based, Black) Compatible Refills: 4C-0.7 refills 【User Reviews】 Highly-rated gear stationery with comments like: "Perfect size for a mini planner pen holder!"
