The Sip of Gold champagne tumblers from SIEGER by FÜRSTENBERG combine the finest porcelain with gleaming 24-karat gold, creating hundreds of reflections when touching a beverage. This gives them their namesake appearance of liquid gold. Handmade in Germany. Each tumbler is lovingly handcrafted and hand-painted in Germany, making it a unique piece – with a wall thickness of just two millimeters.
