The inner liner of the cup is crafted from food-grade 304 stainless steel, offering excellent corrosion resistance, resisting rust and deformation, effectively ensuring drink safety, and maintaining cleanliness even with long-term use. The outer layer is treated with a spray coating process to form a smooth, wear-resistant protective layer with rich colors that are not easy to peel off. Leveraging a double-layer vacuum insulation structure, it effectively blocks heat exchange between the inside and outside, achieving long-lasting heat and cold retention. The 10oz capacity design is compact and exquisite, easy to hold and carry. The upgraded magnetic cup lid prevents falling and opens and closes smoothly.
