Unleash your inner slayer with the official Nichirin Tumbler, a limited-edition Demon Slayer: Mugen Train exclusive from Bearology. Inspired by the iconic sword hilts of the Demon Slayer Corps, this collector’s tumbler combines anime aesthetics with functional design—perfect for boba, iced tea, or your favorite coffee.

Crafted with a dual-compartment windowed interior, the Nichirin Tumbler features a sealed silicone lid and an innovative sword hilt stopper—not a straw, but a stylized plug that preserves drink temperature while turning every sip into a cinematic moment. Sip from the spout as you would a straw without ever breaking the immersion.
