Custom-made stainless steel thermos: your temperature, your style

This isn't just a regular thermos—it's a tangible embodiment of your lifestyle. Crafted from 304 food-grade stainless steel with dual-layer vacuum sealing technology, it maintains beverage temperature reliably across extreme ranges from-20°C to 100°C. Whether it's a steaming cup of coffee in the morning, an icy Americano in the afternoon, or a soothing herbal tea in the evening, it delivers the perfect temperature you desire.


Capacity selection: 350ml (portable and small, put in your pocket and drink on the go), 450ml (commute, meet the needs of half a day of drinking), 600ml (outdoor travel, drink freely once filled), there is always a one that fits your life pace.
Custom Colors: Choose from over a dozen Morandi and metallic shades – vibrant matte coral red, sophisticated light gray, refreshing mint green, or sleek metallic silver – to make your water cup stand out instantly in any crowd.


Whether it's a corporate logo for business presentation, a personal name for privacy, or a motto for spiritual guidance, we can engrave these elements on the bottle with exquisite craftsmanship. Presenting to clients is a way to convey the warmth of a brand.

The bottle features a slip-resistant matte finish for a comfortable grip and fingerprint-resistant surface. Its leak-proof cap ensures water-free spills when packed in a backpack. The seamless one-piece design eliminates hygiene dead zones, making cleaning effortless. Every detail is crafted to elevate your daily hydration experience with refined comfort and sophistication.
