Unlike traditional sauna stones that evaporate water from their surface, the Hukka Höyrykivet Steam Stones are designed with four small chambers. These holes serve as reservoirs, holding approximately 1.35 oz of water and sauna fragrance oils.

As the stones heat up, the water and oils gradually warm, releasing a steady and even vapor infused with fragrance into the air. This ensures a calm and continuous aromatic experience throughout your sauna session.

• Ideal to use in combination with sauna aromas due to the slow release of scent and steam.
• 4 small circular holes per steam stone.
• 100% authentic Finnish Carelian Soapstone made in Tuupovaara, Finland.
• Sturdy Carelian Soapstone is renowned for its high heat capacity and capabilities to withstand harsh environment.
