Microsoft Surface Pro (1) 128GB Black (Wi-Fi) Used

I've bought this device refurbished from Back Market back in Jan 2023. I recently wanted to use a stylus pen but I can't seem to find any that are compatible with it. The only ones that work with it work without Bluetooth (without pairing) which is annoying because I keep accidentally writing when my hand touches the screen.

The ones that can be paired with it can only be used to take a screenshot (using the button on top). The device is glued to the case but it can be easily separated.
