So, I purchased a piece of handheld test equipment that comes with easily replaced (screw terminals) test leads and a cloth case. The unit arrived promptly.
The unusual part of this story is that it smelled of cigarette smoke. Lots of smoke particles everywhere.
I had to wash the cloth case twice in the washing machine. I washed the leads in the washer and they still smelled, so I soaked them in ammonia overnight. Much better.
The case looks pretty sealed, but still haven't put batteries in it.
