Microsoft Surface Pro Flex Keyboard with Slim Pen (Black)

The Microsoft Y8U-00001 is a keyboard and pen bundle created for anyone who relies on a Surface Pro and wants laptop-style control while keeping the tablet form factor. It connects the moment you snap it to the tablet’s edge, yet it can also work over Bluetooth LE when you prefer a little distance. That freedom makes it easy to write long emails at a desk, answer chats from the sofa, or take notes in a meeting without being tethered to the screen.

Typing feels familiar because the keys are backlit for low-light rooms and spaced for comfortable touch-typing. A precision haptic touchpad lets you glide, tap, and scroll with the accuracy you expect from a full laptop. A dedicated Copilot key places Microsoft’s AI assistant within immediate reach, so you can draft text, summarize documents, or ask quick questions without lifting your fingers from the home row.

The Surface Slim Pen tucks into a hidden tray that charges it whenever the keyboard is attached or folded shut. Graphic designers can sketch in Studio Mode, students can annotate slides, and professionals can sign documents the instant inspiration strikes, knowing the pen will be ready each time they pull it out.

When you detach the keyboard, the internal battery keeps it active for as long as forty-one hours, enough for a transcontinental flight or several days of classes. The Alcantara covering adds a soft touch that resists wear and wipes clean with a damp cloth, and the entire unit weighs only three-quarters of a pound, so it slips into almost any messenger bag without adding bulk.

Compatibility with Surface Pro models 8, 9, 10, and 11 means one accessory can follow you through device upgrades. Remote workers, frequent travelers, and anyone who moves between desk and couch will appreciate how easily the keyboard adapts to each environment.
