1. Our bottles are made of food-grade silicone and are BPA-free. Our bottles are dishwasher safe and can withstand temperatures from 50 degrees Celsius to 200 degrees Celsius. 2. The bottle is airtight and easy to fold, reducing the volume of the bottle by more than 80%. The cylindrical shape of the bottom makes it durable and easy to grip. 3. Designed specifically for carrying bottles in a backpack. 4. NOTE: Natural silicone products may have a slight odor or taste. To remove it, add a pinch of baking soda, then fill the bottle with hot water and let it sit for more than 2 hours; then pour out the water and rinse thoroughly. 5. Collapsible water bottle can be put into pocket, purse, backpack or briefcase. Unlike hard water bottles that fill with hot air when empty, it's collapsible and can be rolled up, folded, or flattened for storage. This means it can fit in more spaces and take up less space than any other bottle.
