DianeProcessing Cap, 30 Count

Are these the ones will a small (1/4 to 1/2 inch) plastic trim and not the ones with the sewed trim?

I will be using these outside in the rain for work. Will these fit a baseball cap?

Is one cap used only once then disposed of? or u can use one cap multiple times before disposing of it?

Are these large enough to use when I condition my husband's hair?
