These are a perfectly natural solution to get the best out of your new artisan soap or shampoo bars. If they are not aired well between washes, your bars will become mushy and won't last as long. A soap dish is the obvious answer of course so long as it allows water to drain away. If it doesn't however, you can place a soap saver in the dish (just cut it to size) to aide drainage. If you don't have a soap dish then simply keep your bar on a soap saver instead. Once wet they expand to about 1cm and allow water to drain away freely allowing the bar to dry completely. And of course they are easily washable!
