~Product Introduction~

[Product Name]

Kiryokugan (Igneous Rock) (approx. 50-150mm)

[Description]
*Please wash with water before use.

The ideal rock for sauna stones is said to be plutonic rock, which is a type of igneous rock that cooled deep underground over many years and hardened.
These sauna stones are composed of diorite, a plutonic rock, and diabase, a hypabyssal rock.
Plutonic rocks have a higher density than volcanic rocks like basalt, making them high-quality sauna stones that are heat-resistant and less prone to deformation.
*Common rocks found in riverbeds can crack or burst when heated and are not suitable for sauna stones.

We recommend replacing the stones once a year if used weekly.

△Important Notes△
*The size of the stones will be random.
The quantity will vary depending on the size.
Due to shipping constraints, the weight will be slightly less than 25kg when packed.

*The product images are representative photos, so please expect to receive items similar to the images.

*We pack directly into recycled cardboard boxes, so the boxes may be distorted. We appreciate your understanding.

*We do not accept any complaints regarding the size or color of the stones.

*While the durability of the stones has been tested, we are not responsible for any effects on the human body or accidents resulting from their use after purchase. Please understand this.
