This is a lot of 2 vintage tin litho made in Japan Pop Pop Boats. Simply put a candle in center hole and boats are supposed to move in water. I have not tested these boats. They are sold as is. They appear in fine condition, but there is some rust on inside and some wear to outside of boats. Please view photos. One boat measures 4 inches long by 2 inches wide and the other is 5 inches long by 2.5 inches wide. Shipped with USPS First Class package. Thanks for eBaying with me.
