Clay pack is a new style of hot and cold product. Instead of traditional gel, we use natural clay to provide hot or cold therapy effective. It utilizes a synchronized blend of all-natural, ceramic clay and non-toxic oils to create the ideal thermal transfer source. We design a pouch laminated with fabric, and sew the elastic onto the product. So that we could use the product directly onto any position. The clay pack for shoulder can be used for a home care tool, which enables consumer feel the most comfortable warm and relax.
