Protex vintage rubber pants

Has anyone bought these ru"vintage 1950s rubber pants"? I guess you might hesitate to try using them with their price tag. Anyone know anything about these?

I bought and have a pair of them. I like them very much. They are a bit smallish but still protect my outer clothes when I wet my diaper. If you have the $$$ they are worth the cost.

@doubledbbw Thanks for your thoughts! On being small, wonder if they were perhaps designed exactly to 1950s specifications, not taking into account that many of us have grown larger since then. You'll certainly want to take care of them at the price!
