The OTE 450ml is where precision engineering meets everyday portability. Compact enough to take anywhere, yet spacious enough for your favorite brew – it's the perfect balance. At its core lies a seamless SUS316 stainless steel inner tank – medical-grade, corrosion-resistant, and absolutely odor-free. This is surrounded by an oxidation-resistant layer, a vacuum insulation layer, and a durable 304 stainless steel outer shell – a 7-layer structure that locks in temperature and locks out impurities. The exterior is finished with automotive-grade paint – primer, topcoat, and a protective UV varnish layer – delivering a scratch-resistant, high-gloss sheen that feels as luxurious as it looks. It's built to withstand daily wear while maintaining its elegant appearance. With a 450ml capacity, this mug is effortlessly portable – slips into your bag, cup holder, or backpack without taking up precious space. Whether you're commuting, traveling, or simply enjoying a quiet moment at your desk, the OTE 450ml keeps your drink perfectly hot or cold.
