The Cowrie Lava Shell is a versatile tool. The sachet is specially designed to absorb the activation solution quickly and fully fill the shell in order to maximise performance. Due to its shape, size and thickness the therapist can utilise the heat in a variety of ways, enhancing massage treatments. Nature’s unique design allows it to maintain a consistent heat during use when employing the ‘rocking movement’. This enhancement therapy is recommended with back massage, hands and feet massage and facials. The Lava Gel that powers the shells is available in two formulas: Facial for facial massage and Trigger for back massage and hand and feet massage.
