Portronics Key7 Combo — full-size wireless keyboard and optical mouse, in the black and orange colourway. Genuine Portronics, used but fully working: both the keyboard and mouse have been tested with the included USB receiver before listing.

A tidy, no-fuss upgrade for any desk setup:

One 2.4 GHz USB receiver runs both the keyboard and the mouse  — a single dongle, one free USB port, no Bluetooth pairing faff.
Genuinely plug-and-play — no drivers to install,  and it works with Windows, macOS and Linux. 
104 soft keys  for quiet typing — the dual-textured keycaps look sharp and keep noise down, so it’s well suited to shared offices and video calls.
Full-size layout with a proper numeric keypad, plus 12 shortcut keys  for media, volume, email and browser.
