A white mug featuring the TAMIYA logo. At first glance, it's a simple mug with a star mark, but when you pour in hot water (50-60 degrees Celsius), 36 different models from the MM series appear in gray silhouette, transforming it into a fun mug! (See photo 2) Although unused, it has been stored at home for a long time. ★Size: Diameter (outer) 75mm x Height 90mm. Weight: 310g. Thank you for looking.
