All of my soaps are hand poured and cut. Every bar is one of a kind. The weight is measured after at least 8 weeks of curing but may shrink slightly after that time. Your bar will always weigh as much or slightly more than the amount on the label. For best results and longest bar life, allow your soap to dry between uses. Soaps are wrapped in a biodegradable film but can be packaged naked if you prefer.
