22oz “Tiny Sister Goes Beast Mode” Anime-Style Bluetooth Speaker Tumbler – Manga Chaos Edition

22oz “Tiny Sister Goes Beast Mode” Anime-Style Bluetooth Speaker Tumbler – Manga Chaos Edition

This 22oz stainless steel tumbler features a wild, high-energy manga-style wrap showcasing one small but surprisingly aggressive sister unleashing her full “don’t test me” power. Below her, the calmer, bamboo-chewing version of her is just trying to look adorable and mind her business. It’s a perfect blend of cute and unhinged—just like life.

And because normal cups are boring, the bottom includes a built-in Bluetooth speaker, so you can sip your drink while playing hype music, battle anthems, or angry workout tracks that match the chaotic energy on the tumbler.

Each cup also comes with a metal straw and a cleaning brush, so you can stay eco-friendly while looking dangerously cool.
