Capacity: 450mlHEALTHY， ECOFRIENDLY CHOICE: Elder Glass water bottles not only keep water deliciously fresh and cool， they're superior to a collapsible water bottle they won't leak or puncture. They're also reusable， making them better for you and the environment.WIDE MOUTH DESIGN: With a wide mouth opening you can more easily use our bottle for fruit infused water， tea， or even adding ice. It's also easier to clean and lets you take bigger gulps instead of little sips.1. MULTIPURPOSE DESIGN: Made of tough， durable glass， the Elder Glass water bottle is classier and more professional than a stainless steel water bottle， making it better for work， the gym， Pilates or even Yoga. 2. It's also ideal size for automobile cupholders and backpack mesh pockets.3. EASY GRIP SILICONE SLEEVE: Surrounding and protecting our glass bottle is an easy-grip silicone sleeve that ensures your hand won't slip or slide due to moisture， condensation or while moving. It also makes it easier to hold than an aluminum water bottle that lets cold sweat reach your fingers.
