Key Features: Why This 500ml Vacuum Tea Cup Stands Out

1. Precision Temperature Control

- 18-Hour Hot / 24-Hour Cold Retention:

Third-party tests confirm the cup keeps tea at 68 degree + for 18 hours and iced beverages below 10 degree for 24 hours-ideal for green tea, oolong, or cold brew. The 3.2mm vacuum layer blocks 97% of heat transfer, while the copper-coated interior reflects thermal energy 25% more efficiently than standard stainless steel.

- Tea-Specific Design:

The 500ml vacuum tea cup includes a removable stainless steel infuser (mesh size: 0.3mm) for loose-leaf brewing. The 55mm-wide mouth accommodates tea bags, ice cubes, and easy cleaning.

2. Eco-Friendly & Durable Construction

- 304 Stainless Steel Body:

Made with 18% chromium and 8% nickel, this material resists tea tannin stains and corrosion. Accelerated aging tests show zero rust-3x longer lifespan than 201-grade steel.

- Plant-Based Lid Components:

The silicone seal uses 65% rice husk-derived materials , reducing plastic waste by 1.2kg per 100 units produced.

3. Ergonomic & Travel-Ready

- Non-Slip Grip: Diamond-cut grooves on the base improve grip strength by 35%

- Universal Compatibility: Fits 90% of car cup holders and standard dishwasher racks.
