Meet the Kathartik Kup—our stainless steel shaker designed to keep your drinks tasting fresh and free from lingering odors or harmful chemicals. Say goodbye to the stale, funky odors that cling to plastic shakers. Our non-insulated, food-grade stainless steel design ensures that once you wash it with a little dish soap, yesterday’s protein shake doesn’t come back to haunt you.
What Makes the Kathartik Kup Special?
Easy to Clean & Odor-Free: Unlike plastic, stainless steel rinses clean every time—so no more lingering funk! A quick rinse with dish soap leaves it clean and fresh every time.
Lightweight & Easy to Carry: Less bulk, more freedom. Toss it in your bag without the extra weight of insulating layers.
Smart Material Choice: Stainless steel helps you avoid plastic exposure, including BPA and similar chemicals (BPS, BPF, BPAF, TMBPF)—all of which can pose hidden risks.
Durable & Eco-Friendly: Crafted to withstand everyday bumps and drops. Ditching single-use plastic bottles and repeatedly replacing smelly plastic shakers helps reduce waste.
