Thank you for viewing! This is a Lampe Berger catalytic fragrance diffuser. I purchased it about 20 years ago and used it a few times, then stored it. It's quite old, so I'm not sure if it works properly. Please check the remaining oil level in photo 8. (The oil is also quite old, so I'm not sure if it will be effective.) Please consider purchasing this item, understanding that it is a personal, long-term storage item. ↓ The following is a quote from the website ↓ This is a set of Maison Berger Paris (formerly Lampe Berger) aroma lamps. Maison Berger Paris was developed in France in 1898 by pharmacist Maurice Berger. Its unique patented catalytic combustion system has the effect of deodorizing and antibacterial action against bacteria, tobacco, pets, and other odors in the air. The set includes the lamp body, eucalyptus and Neutre (fragrance-free) special aroma oil, a wick (burner), a funnel, and a snuffer cap. The main component of the special oil is alcohol, and if stored correctly, the expiration date is unlimited. ⭐︎ We strive for safe and courteous transactions. ⭐︎ We welcome purchases without comments, but please purchase if you understand that this is a used item.
