This friend helped me fulfill my dream of becoming a programmer, and thanks to him I moved to Europe!
I got a new machine at work, so it’s time to give my friend a new life in new hands:)

Everything is working. The only issue is an old battery, which gives only 30min without charger.
For the entire period of operation 2 pixels have faded and the rubber on the screen crumbled a little bit in the up-right corner (see pics).

THE CHARGER IS NOT INCLUDED!
I put 2 UsbC-Magsafe2 adapters, both work, differ only in shape.
Any charger 65W+ with usbc will fit; previously I used Acer's and now GaN Baseus.

I can sell the charger separately, send me a message and I'll create a new item or we come up with it another way. My current desk solution is "Baseus USB C Charger, 65W USB C Power Supply 4 Port GaN III", which also charges this macbook.
