What item have you been using on a daily basis for the longest amount of time?
Sometimes I will use something and realize I've owned it forever. It's a nice change in our throwaway reality. I think my personal record is a bicycle multi-tool I got for one of my first bikes, ~25 years ago. Still have it, still use it. When it comes to electronic devices I have a Panasonic mini Hi-Fi from ~2005. Never felt like changing it.
My Secrid wallet. Bought it around 2016, use it every day and it's still in very good condition. I was very happy with it when i bought it and still am. It was a bit on the expensive side but i like to pay for quality.
French ID cards were bigger size than standard credit card for a long time and thus I have used the same wallet of that size for like over 12 years now. It's time for me to replace it but as I don't need it to be this big anymore I have no clue about what I want
