This is a refurbished replacement bottle of the Eros style. The Eros bottle has a special glass lip that coveres the entrance of the bottle which helps to redirect oil away from the center of the glass. This helps extend the life of the unit. Each unit was returned in the kit by a customer but still fully functional and was cleand to like-new status. There are no functional differences between new and refurbished bottles. Comes with a replacement top.
