Letting water sit on soft fruit will speed up the process of them getting mushy and gross. So you wash them, put them in these, and the air circulates to help dry them off and they keep a little longer. I wouldn’t try these with blueberries, but it looks like they’d work for strawberries, cherries, small apricots, etc. the lack of a hole in the bottom is probably because they’re not for actively straining things. The size is probably about right for a single pint.
