From Okinawa comes a collaboration between Hotel Nikko Alivila and the innovative Trim Inc. Together, they are crafting an unconventional aroma stone, birthing the eco-friendly material known as “Super Sol.” This substance, originating from the island itself, is formed from the remains of discarded glass bottles.

“Super Sol” is a lightweight, porous substance crafted by reimagining waste glass as a valuable resource. Through a process of crushing, grinding, firing, and foaming, this material emerges as an environmentally-conscious, soil-restorative agent. Its exceptional water permeability, retention, and fire resistance qualities make it indispensable for constructing a sustainable, resource-recycling society. The resulting aroma stones, imbued with the essence of “Super Sol,” possess an outstanding capacity for water absorption and long-lasting aroma diffusion.
These versatile aroma stones require no electrical power source. They effortlessly integrate into the modern lifestyle, whether adorning the entrance of a home, accenting an office desk, or nestled beside a pillow, inviting slumber with a soothing scent. A discreetly placed hole allows for easy hanging, adding to the stone’s charm. To indulge in the enticing fragrance, simply infuse the stone with 2-3 drops of Alivila’s signature White Gardenia aroma oil, or select an aroma oil of your personal preference. Available for purchase on their online shop.
