My Hallmarked Britannia Silver Tumbler Cups is completely handmade using thick silver, this tumbler cup has been hallmarked in Britannia Silver, a higher grade of silver than sterling silver, making it an extremely unique gift. With a beautifully mirror polished exterior, and rich gold gilt interior, this cup is perfect for drinking any tipple, and can also be used as water cups. The tumbler cup is completely hand made with substantial weight left in the base which allows the tumbler cup to ‘rock’ or ‘tumble’ without the cup or it’s contents spilling over.
