??Regarding the black spots on the bottom:
The 2-3 black or gray spots, approximately 7mm in size, visible on the bottom of vacuum flasks (especially glass ones) are not mold or rust. They are spacers (mats) that support the glass in the vacuum double-wall structure.
Why do they appear black (or gray)?
* Structural Role: The space between the inner and outer glass walls of the vacuum flask is a vacuum. To maintain a consistent gap, a clay-like mat is inserted.
* Reason for Color: The silver coating applied to the glass (a process to enhance heat retention) does not adhere to the mat area. As a result, it appears as black or gray dots showing through.
Thank you for viewing.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
