I will admit I have not tried actually eating with these chopsticks, nor will I ever. But it you want a dignified Japanese styled decoration that can sneak a vocaloid tribute in that only fellow otakus will notice then these are hard to beat. The design is beautiful on its own and the subtle nod to the vocaloids using music imagery and their respective colors is truly wonderful. Its almost enough to get me to learn how to actually use chopsticks...
