My DD has too often been my dehydrated daughter. Her water bottle lid cracked leaving her with no water bottle for high school. I let her borrow my FlyLady water bottle . When she arrived home 12 hours later I asked her how her water bottle worked. She said those famous words, “I drank lots of water!”
The stainless water bottle will keep your water cold. You fill your water bottle up with ice and water, you drink it, you wash it out and you reuse it.
You save money and you aren’t throwing plastic bottles into the land fill.
