It all started when I purchased two 4" silicone molds from this company and really loved it. After that I have been extremely satisfied with everything I've ordered from Nurture Soap so far. Now that I am moving to bigger batches, I made sure to get my mold from the same company. Its stiff enough but not too much to make it difficult to remove the soap. My loaf comes out straight unlike what you would get with molds that are too soft. And as a bonus, its so easy to clean!
