When it may not be suitable

How to use

Fill the bottle with your preferred hot or cold beverage, leaving a small amount of space at the top to ensure the cap seals correctly.

Usage recommendations

For optimal temperature retention, pre-chill the bottle with cold water for cold drinks or pre-heat it with hot water for warm beverages before filling. Avoid placing the bottle in the freezer or microwave to prevent damage to the vacuum insulation and materials.
