Vacuum Insulated Mug 300 ml

Product Description

• Capacity: 300 ml (approximately 10 fl oz): This specific volume makes it perfect for a single serving of a standard coffee, a generous cup of tea, or a refreshing cold drink. It's an excellent size for commuters, office workers, or anyone who enjoys sipping beverages throughout the day.
• Vacuum Insulation Technology: This is the core of its functionality. The mug features a double-wall construction with a vacuum sealed space between the inner and outer layers. This vacuum acts as a barrier, preventing heat transfer via conduction and convection.
  • Temperature Retention: This results in superior thermal performance, keeping:
    • Hot beverages hot: Typically for 6-8 hours, ensuring your morning coffee stays warm on your commute or at your desk.
    • Cold beverages cold: Often for 10-14 hours or even longer, keeping iced tea or water refreshingly cool for hours.
  • Copper Coating (Optional, but common): Many high-quality mugs include an additional copper layer on the inner wall to further enhance heat reflection and improve insulation efficiency.
