Because asked, this is said 25 year old leather jacket. At this point it's flexible and soft as a glove. I have no doubt it’ll last longer than me.
While I'm on the subject of taking care of your stuff, please learn to repair your clothes or find a good local tailor. I ripped the inner liner before, and the nice lady around the block fixed it right up for me. Buy shoes you can re-sole. Get quality clothes you can mend. These things are more expensive once, but then you can keep them for years.
@worldsendless Give it a shot! What's the worst outcome? You can't get it back on right and have to cut it off to start over? No harm done!
