Our vacuum-insulated water bottles are engineered for superior performance. The core benefit is exceptional temperature retention, keeping beverages cold for up to 24 hours or hot for up to 12 hours. This is achieved through a double-wall vacuum insulation technology that creates a barrier against heat transfer. Beyond performance, they are built to be durable, leak-proof, and 100% taste-neutral, making them perfect for daily use, outdoor adventures, or as premium corporate gifts.
We prioritize quality and safety in all our materials:
-
Inner Liner & Outer Wall: Made from high-grade, rust-resistant 304 or 18/8 stainless steel.
-
Insulation Layer: A precision-engineered vacuum seal between the double walls is the key to temperature control.
-
Lid Components: We use food-grade, BPA-free plastics. Options also include stainless steel lids and bamboo tops for a more natural aesthetic.
-
Coating: The exterior can feature a durable, non-toxic paint finish, a powder-coated matte texture, or a polished stainless steel look.
We provide a comprehensive suite of branding techniques to make your bottles uniquely yours:
-
Laser Engraving: Offers a permanent, sophisticated, and tactile finish for logos and text. Ideal for a high-end, durable brand impression.
-
Digital Printing: Allows for full-color, complex artwork, and photorealistic images. Perfect for vibrant designs and patterns.
-
Powder Coating: You can choose from a vast palette of Pantone-matched colors for the bottle’s body to align with your brand identity.
-
Debossing & Silk Screening: Classic methods for crisp and clean logo application on various surfaces.
-
Custom Lid Colors & Accessories: Match the lid color to your brand and add custom straps or carabiners.
Yes, our standard MOQ for custom vacuum bottle orders starts at 300 units. This allows us to maintain high quality and cost-effectiveness.

We gladly offer sample orders (1-10 units) for quality verification and marketing purposes before committing to a full production run.
Once your design is finalized and approved, the standard production lead time is 15-25 days. This timeline includes material preparation, manufacturing, quality control checks, and custom packaging. Shipping time will vary based on your location and chosen freight method (air or sea). We provide a detailed schedule upon order confirmation to ensure it aligns with your campaign or launch plan

We recommend a resolution of at least 300 DPI to ensure your branding is sharp and clear. If you only have a JPG or PNG, our team can often vectorize and optimize it for you, subject to a small design fee.

Consumer safety is our top priority. All materials that come into contact with beverages are certified food-grade and BPA-free. Our stainless steel is FDA-compliant, and we can provide LFGB and REACH certifications for clients requiring compliance for European and international markets.
