Went to Target and bought a set of glass containers with plastic caps - not sure what brand. At any rate, they are an okay size for soaps, which is what I bought them for. So far I have two soaps safely stored inside the bowls. BUT, I cannot get the plastic lids to stay on the bowls! They seem a bit small, and no manner of twisting, torquing, pulling, whathaveyou will make them seal. My question is, is this a problem for the "safe" storage of my soap?
