Before purchasing, please confirm if the following imperfections are acceptable. Due to the manual demolding process for the flasks, black marks, spots, streaks, and transparent marks on the glass surface are normal occurrences during production. These are located in the interlayer between the glass and the outer stainless steel layer and do not affect usage. https://live.staticflickr.com/65535/52850164413_d2e08174ec_n.jpg **!!Please note that the glass liner is fragile.

Cuppa28 Series Double-layer vacuum-insulated glass liner, plastic semi-transparent casing, plastic lid Includes a "CAMEL" wooden spoon Production: Made in Hong Kong, entirely handmade. Hong Kong brand with a long history. Capacity: 280ml Dimensions: 7.8cm (W) x 16.3cm (H) Materials: PP & ABS casing and lid / PP & ABS / Silicone auxiliary parts / Glass vacuum interior Glass Liner Suitable for tea, traditional Chinese medicine, coffee, etc. Standard stainless steel flasks can alter the taste of tea, coffee, etc. Furthermore, some traditional Chinese medicines are acidic and are not suitable for storage in stainless steel flasks. Glass-lined vacuum flasks offer a significant advantage, preventing flavor alteration and allowing for the safe storage of traditional Chinese medicine. Inspecting Your Flask Upon receiving your flask, please ensure you: 1. Understand that black marks, streaks, and transparent marks inside the flask are normal during the production process and do not affect its performance. 2. Be aware that due to hand-spraying, the surface lettering may be slightly blurred, and most items may have minor scratches. After the above inspection and testing, if there are no issues, you may proceed with use. Instructions for Use: After filling with ice water (or rinsing with cold water), do not immediately pour in boiling water. Similarly, after emptying boiling water, do not immediately rinse with cold water, as the drastic temperature difference between hot and cold water can cause the glass to crack. Do not use the flask lid as a cup. Do not drink directly from the flask. The flask is not designed to be leak-proof. Please avoid shaking or inverting the flask. Keep children away from the product or when it contains hot water. When used correctly, glass-lined products can typically maintain temperature for up to 24 hours. Glass liners can safely hold liquids such as tea, coffee, and traditional Chinese medicine, which may degrade easily. The glass liner has a double-layer structure. The printed pattern ( "black dots") visible inside the liner serves to separate the two glass layers and is located between the inner and outer walls, not in contact with the liquid. To enhance the thermal insulation of the glass liner, the surface of the inner liner facing the vacuum layer is coated with pure silver through a sedimentation process. The liquid contained in the flask will not come into contact with the silver.
