Description Made of polished brass and an inset of aluminum, the air gap between the inset and casing provide perfect insulation to keep the wine ice cold. The cooler can also serve as a centerpiece with flower arrangements. Designed in 2001. Skultuna products are made of solid brass without surface treatment if nothing else is stated. Brass is a living material that oxidizes over time and needs care by its owner to keep the shine through the ages. The oxidize protects the metal and prolongs the lifespan, on the inside of vases and flower pots this is desirable and should not be removed. On the outside, it’s a matter of taste whether you polish it or not. Brass will naturally darken over the years and fingerprints, grease, water etc may leave stains on the surface. If you wish to keep the high polished surface you will need to polish the brass regularly. How often varies depending on the environment, air quality, how you handle the brass and more. If the outside gets wet due to condensation, try to wipe it of once in a while during the use. But most importantly, never leave the cooler to self dry! Make sure to completely dry the brass surface after use, then polish it before putting it away. 23.5 x 22cm
