Ordered these collar stays after losing all the ones that came with recent new shirts for my husband and subsequent curling collars.  I couldn't figure out why he stopped wering some of his new shirts and he said the curling collars looked sloppy.  Apparently I washed the shirts with the collar stays and lost them - bought these and there's a size for everyshirt and allows me to keep the case on the washer to remind me to take out before washing and put in when they come out of the drier.

Great seller too - quick and efficient.
