Query: They rusted in the sink after one use.

Total waste of money. I used these once and then soaked them in the sink before cleaning and they rusted at the joints! I don't want to use something that rusts on my food so I threw them out.They were also poorly constructed. The metal was very flimsy and they didn't lay completely flush with the bottom of my pan. I used them to make eggs and some of the egg whites leaked out so they didn't really created perfect circles. I could have dealt with that but rusting was a deal-breaker.
