Whether it is a personal customization, business gift, reunion souvenir, party gift, company event commemoration, or staff welfare, this insulation mug is a good choice. A good spray painting process treatment can make the adhesion stronger and the color more vivid, not easy to lose paint. The smooth and delicate touch makes it a pleasure to hold. Using a five-step process, the copper-plated reflective layer reduces vacuum radiation and blocks heat convection and conduction, making the insulation effect significantly better. The mirror-polished inner liner is smooth and delicate and does not hide dirt, making it more hygienic and healthy, and easier to rinse. The inner lid is upgraded to 304 stainless steel and the silicone seal prevents water leakage, making travel more convenient. Measuring 8.86*2.56 inches, this custom 16oz creative wood grain business stainless steel insulated mug. Usage Scenarios: Office supplies, school stationery, corporate promotions, trade show giveaways. Tailored branding: Supports logo imprint and design personalization. Product Highlights: BPA-free, leak-proof, travel-friendly.
