- DIRECTIONS FOR USE: We recommend rinsing the flask thoroughly before first use. If you experience taste mix ½ a teaspoon of BAKING SODA with water, shake and rinse. Users have also found the following to be useful: Fill with MILK, shake, and rinse. Add drops of lemon. Let an orange peel or tea bag set in the flask for a couple of hours. To hydrate, simply softly bite the mouthpiece and press the soft flask and enjoy! The harder you press, the faster the liquid will exit.

### ⭐ It leaks right out of the box

Filled it with water and left it on the counter. It leaked. Tried to tighten it up even further, kept leaking. Useless

### ⭐⭐⭐⭐⭐ Buena calidad y precio
*by A***. on 4 October 2023*

Después de probar varias marcas y precios, entre ellas las de decathlon, os puedo asegurar que esta pequeña y flexible botellita es cómoda de llevar en bolsillos de mallas o mochilas de Trail. Lo mejor de todo es que el agua NI SABE a plástico, como si me pasaba con las anteriores compradas. Muy recomendable. También he vomitado la de 500 ml.
