Melt the
tension

Bear down on a tight muscle with a cold, hard ball and it braces back. Mochi adds a steady, relaxing 42°C as you work, so the muscle softens and releases instead of fighting you — pressure finds the knot, heat lets it go. Heat therapy and self-myofascial release, in one ball.

Anatomy - What's inside

Four layers
One purpose

Every mochi is built from the core out. A heat cell, a bladder, a soft foam layer, and a silicone skin.

  1. 01

    Silicone skin

    Food-grade, skin safe, body-safe temperate.

  2. 02

    Soft foam

    Absorbs PCM expansion when heated, prevents overexpansion and hardening of the ball.

  3. 03

    PCM silicone bladder

    Prevents leakage.

  4. 04

    PCM heat cell

    Phase-change material. Holds the heat for 40+ minutes.
