This handy commuter tumbler comes with two colorful "To Aru Kagaku no Railgun" images that can be changed anytime you like! Kuroko playfully tackles Mikoto on one image; all the girls pose in swimwear on the other. The tumbler is about 18cm tall (with the lid on) and 7cm wide, and it's insulated to keep hot drinks hot and cold drinks cold. The lid snaps on securely to prevent spills, and it arrives in a sturdy box to make it a great gift!
