Description

Product Details:
Crafted from premium 304 stainless steel, this 500ml double - walled vacuum flask utilizes advanced insulation technology. It keeps drinks piping hot for 12+ hours and ice - cold for 24+ hours. The wide mouth enables easy filling with ice or cleaning, and the leak - proof lid (featuring a secure silicone seal) guarantees no spills during transit—ideal for on - the - go teams or event giveaways. The matte finish (exemplified by lavender) feels premium and resists scratches, maintaining a polished look even after heavy use.

Customization Capabilities & Options:

  • Color: Match any Pantone shade for the outer coating to align with your brand’s identity.
  • Branding: Laser engraving (for sharp, permanent logos/designs), UV printing (for vibrant, full - color graphics), or embossing for a tactile logo feel.
  • Packaging: Custom boxes, sleeves, or gift sets—we’ll tailor packaging to your marketing needs (such as branded unboxing experiences for client gifts).

Supply Chain Assurance:
We operate a vertically integrated supply chain. From raw material sourcing 304 stainless steel to production and delivery, we ensure quality at every step.
Enjoy faster lead times for bulk orders and flexible MOQs (starting at 100 units) to suit startups or large enterprises. All products meet FDA, LFGB, and EU safety standards.

Business Application Scenarios:
Perfect for corporate gifting (employee onboarding kits, client thank - you gifts), promotional events (trade shows, conferences), hospitality (hotels, cafes for branded in - room amenities), or employee wellness programs (encouraging hydration with stylish, reusable bottles).
