I found this little doohickey in my toaster, along with a little piece of paper. I thought maybe it was a little foot for a counter appliance, but nothing is missing anything. It obviously covers a nut or something, but I can't find what it goes to. It is fairly soft and pliable.
I never know what I'll find in the toaster.
EDITED at 11:30 pm to add: Found it!
It is the covering for the on/off switch for my flashlight. That was driving me crazy. Mom often carries it around (no batteries in it), I never thought of it as unsafe before. I have now hid it in the cupboard.
