IMPERIAL Calabaza Rustica Beautiful and very high quality mate cup made of pumpkin, covered with black leather and a metal ring from ALPACA. The hand decorated metal ring makes this cup unique and a work of art! The size, color and decoration of the product may vary from the picture as it is a natural product. While using the mate-cup a discolouration of the pumkin takes place. This is a natural process which occurs through the absorption of the tea. Before the first use of the cup it should be "cured" in order to ensure a longer life. Any light scratches on the metal ring can be removed with a cloth and polishing paste (for cutlery).
