Material & Structure：

• Both inner and outer walls are made of 18/8 (304‑grade) stainless steel, corrosion‑resistant and easy to clean.
• The middle layer is a highly conductive copper plate that rapidly absorbs and blocks heat transfer, significantly extending the cold‑holding duration.
• High vacuum is applied between the three walls, minimizing convective and conductive heat loss.

Measured Cold Retention

• At 20°C room temperature, with 0°C iced water, the tested cold retention lasts over 48 hours.
• This product has been cold‑tested against 60+ leading brands under identical conditions, with results reflecting its cold‑keeping performance.

(Actual duration may vary with ambient temperature, opening frequency, and other factors.)

Surface Decal-Surface finishes: 8 options including spraying, powder coating, gradient, 4D sculpture, water transfer, air transfer, heat transfer, and electroplating – achieve matte, gloss, textured, or 3D effects.

Logo Printing-Silk printing for simple marks, laser engraving for permanent wear‑resistance, 3D printing for dimensional feel, and heat transfer for complex full‑color designs.

Design & capacity-Shape and color schemes can be adjusted per customer requirements (OEM/ODM), with fixed 128oz capacity and customizable appearance details.
