They found that although soap is the combative option to dirt, locals often understood it to be a contaminated object, which makes it difficult to keep near the toilets without feeling like it may be soiled in the process. Overtime the team developed five different prototypes and landed on the Tab Soap. It is made from sustainable bamboo-based textiles that are doused in soap. Once it is used, the remnants can be disposed of in the toilet to decompose by itself.
