It’s not just a cup—it’s a piece of Demon Slayer
If you’re a real fan, this tumbler will hit instantly. The design is based on Tanjiro’s Nichirin sword, and the lid even has a sword-hilt plug that looks just like the ones in the anime. It’s not a straw, but you sip through the top—so it keeps the look while still being super usable.
Surprise Collectible Card
Every tumbler comes with a mystery “credit card skin” inside the box. There are 7 in total—some are shiny holographics, and 3 of them are rare. It’s a fun bonus for fans who like little surprises and collectibles.
