In our daily life, the little peices of soap are really annoying. Too small to use, too wasted to lose. But now you'll have no worry with the Soap-Sandwich. It has a laundry ball inside so that you can use up the last drop of soap without any wasting. While the soap gets smaller, the laundry ball is exposed little by little.The bumps on it would increase the fricions to prevent sliding. At the same time,the laundry ball can be used to do daily washings when the soap is gone.
