Keychron K3 model, a low-profile US layout keyboard. It's very thin, featuring easy typing and a stylish design. Manufacturer: Keychron Model: K3 Layout: US layout Connectivity: Bluetooth (wireless) and USB (wired) compatible Condition: Purchased on Mercari and used for a short period, but I'm selling it because the US layout didn't suit me, so I bought a JIS layout keyboard instead. Operation has been confirmed and there are no issues, but please understand that this is a used item that has been used a few times.
