I keep them in the the provided container attached to the bike key. So I don't see myself losing them.
What have you got?
That's the exact problem.
On your bike key it unscrews as you ride and when you check again the container is gone.
And it's that one time when you didn't use them for whatever reason.
In my case I literally dropped it in front of me because that tube is so finicky to handle and then I just couldn't find it.
Suspect it may have dropped into the bike.
