Water Tank Cover - White is the original spare part of the K-fee TWINS II, TWINS II & LATTE and GEO capsule machines. The capsule machines of the K-fee TWINS II/GEO family have a water tank on the side. It has a cover in the same color as the main body This cover only fits the water tank of the TWINS II/GEO and TWINS II & LATTE. The TWINS (without "II") has a smaller water tank and therefore a smaller lid. The water tank is available separately.
