MIYASHIRO STUDIO Onsen Saru Air Freshener

Unlike standard fresheners that are merely sprayed with fragrance, this card is fully immersed in essential oils. This saturation method creates a more robust, layered scent profile that mimics the natural, woodsy aroma of a Japanese hot spring rather than a synthetic perfume.

Because the card is designed to be refillable, you can simply apply a few drops of your own essential oil or a compatible refill vial directly onto the card stock. This allows you to extend the life of the product well beyond the initial four-to-six-week duration.

The scent is designed for smaller, enclosed spaces like cars, closets, or small offices. While it provides a noticeable, calming atmosphere in these areas, it may be too subtle for larger, open-concept rooms or vehicles with high airflow.

The card is made of absorbent card stock designed to hold the oils securely. However, to prevent any potential transfer, we recommend hanging the card freely rather than placing it directly against fabric, leather, or plastic surfaces.

The 'Snow' note is an abstract, crisp element designed to evoke the cold, clean air of a mountain hot spring. It balances the earthiness of the Matsu Pine and Cedar wood, adding a sharp, refreshing finish that prevents the woodsy notes from feeling too heavy.
