Hand-finished copper tumblers, 420ml capacity. Set of 2 (same color), gift-wrapped. I intended to give these as a gift but missed the opportunity, so I'm selling them. When I checked the condition of the product upon purchase, there was a slight black pattern on the inside of the cups, but I was told it's a natural part of the manufacturing process and not a problem. - Capacity: 420ml - Material: Copper - Design: Hand-finished - Color: Silver
