I’m on the hunt for a Fairphone 4 in good condition. If you’re offering the full package with accessories (including the earbuds) and warranty transfer, I can stretch to 350 euros. If it’s just the phone, my limit is 300 euros. I’m based in Tampere but can arrange a meetup in Helsinki.
If you have a Fairphone 4 that fits the bill, let’s me know in the comment section.
