I've been trying to find a good cheap soap dish (that I could buy six or more of) preferably ceramic that has a lid. Unfortunately in my hunt all I usually come up with are ones without lids or ones with lids that are $15 to $20 a pop. I'm currently using small ceramic dessert dishes, but have no lids and am concerned about the soap oxidizing due to being out in the open like that. Any thoughts or suggestions on this?
