I purchased a beautiful item that was used once on a flea market site. I am selling it because I missed the opportunity to use it. The que Bottle, a collapsible water bottle born in San Francisco, can be stored compactly after you finish drinking. This water bottle has a simple construction made of two materials: silicone and stainless steel. It can be used safely by children and adults alike. After drinking, it can be folded in half, so it doesn't take up much space in your commute or school bag, making it easy to carry around! The wide mouth design makes it easy to clean with a bottle brush. Capacity: 600ml The color is white, but it also looks like a light purple. Product Details Bottle - FDA/LFGB certified food-grade silicone / Cap - 18/8 stainless steel (silicone is vegan-friendly) Leak tested BPA-free, does not retain taste or odor Dishwasher and refrigerator safe / Microwave not allowed 355ml: 16cm when extended, 10cm when folded; 600ml: 21cm when extended / 12cm when folded Due to the single-layer silicone construction, it does not have cold or heat retention functions. Important Notes: Be sure to sterilize by boiling before use after purchase. Remove the cap while the bottle is extended, and boil it in a pot large enough to submerge the entire bottle in boiling water for about 15 minutes. You can put hot drinks in it, but be careful of burns as it is not a double-layer structure. (Heat resistant to 200 degrees Celsius)
