Hatsune Miku Characters Heat Changing Mug

Hatsune Miku features alongside 2 of her virtual band mates, Kagamine Rin and Megurine Luka on this 10oz heat changing mug. When cold the mug shows the three characters on a black background, but add hot water and watch this design change before your eyes! The background changes to a pale blue with multi-coloured stars, a patterned circle appears behind each character and their names change from black to purple, pink and blue! This would make a great gift for any Hatsune Miku fan!
