Shellista is made 100% with natural ingredients derived from scallop shells caught in the Okhotsk Sea in Hokkaido. Although it only contains natural ingredients and no synthetic surfactants, preservatives, fragrances or coloring agents are used, its sanitizing and deodorizing effects are stronger than other similar products. In addition, Shellista is eco-friendly as it is made by reusing scallop shells that are otherwise discarded as industrial waste. As part of its social contribution, the company offers job assistance to people from nursing homes in its production facility — they help fill the product containers with materials. Also, Shellista is Halal certified and a JOCA recommended Product.
