This is a mug from the "Deutscher Weihnachtsmarkt Osaka" (German Christmas Market Osaka). This popular event is held every winter (around November to December) at Umeda Sky Building in Osaka, recreating a traditional German Christmas market. This mug is an original cup sold at the venue for hot wine (Glühwein) and other drinks. I forgot which year it was from because it's not written on the cup, but it's a limited-edition item with a different design and color each year. This is a heart-shaped mug set with a snowflake design. The design combines when the two mugs are put together, and it's compact for storage. There is a small chip on the white bottom. I haven't used it since bringing it home, but it may have chipped during the transport (see photo 5). Side of the heart: Approximately 7.5cm (measured as in photo 14) Height: Approximately 9cm Capacity: Approximately 180cc - Color: Red and White - Design: Snowflake pattern - Shape: Heart-shaped mug - Text: Deutscher Weihnachtsmarkt - Material: Ceramic - Type: Set of two mugs Thank you for looking.
