A car scent diffuser using essential oil with a ceramic disc. Apply 4-6 drops of essential oil on each side of the ceramic tablet (included) at first use then insert into the thermal heat plate under the stainless-steel cover. The heat accelerates the diffusion of the essential oil to scent your car. Each disc lasts approximately up to 1 month with regular use; apply additional drops of essential oil to the ceramic disc when the scent has faded. Set includes 2 ceramic discs and one 5ml bottle of Serene House essential oil. Replacement discs sold separately. Powered by 12V outlet or USB port. Adjustable angle to fit all car consoles.
