I have never seen or heard of this until reading your post. I think the idea makes a lot of sense. My only concern would be how well it dries due to bacteria growth? Keep us posted as I want to know more myself!
I've used a nylon mesh soap bag before, and it does make lots of lather, but drying the soap in the bag wasn't all that effective. After trying it for a week, I decided to stop using the bag.
I was hoping you guys could fill me in.
Hmm...never used one but maybe you could take the soap out and let them dry separately, and when you need to use it again you just slip it in the bag. Where did you buy yours?
