Once you experience @aroma and the way in which scent can contribute to your bedtime (and daytime) rituals and lifestyle, there is no reason to limit that to your own home. The Mini Stone allows you take @aroma with you, and is an essential travel item. Fragrance your hotel room with what is familiar to you and that which helps you sleep.
2 Amakusa porcelain stones are within the travel case, and require just a few drops of your chosen essential oil to dissipate overnight.
