This non-electric aroma diffuser is designed for personal, close-range use. Instead of filling large rooms, it gently releases fragrance when placed nearby, making it ideal for those who prefer a subtle scent experience. Inspired by Japanese living culture, it can be used safely without fire or electricity. Simply add a few drops of essential oil and place it on a desk, bedside table, or in other small personal spaces. Not intended for large rooms or open living areas. Aroma oil is not included.
