## Description

FLSK Thermos Bottles! Keeps drinks hot for 18 hours and cold for 24 We believe that a drinking bottle should make your life better and easier.Unique VICC ® Technology. Using our unique Vacuum Isolated Copper Coating - short: VICC ® Technology - FLSK thermos bottles keep your drinks hot for 18 hours and cold for 24.

Great bottle and keeps water cool all day long.

    Water bottle for sparkling water
  

*by S***N on Reviewed in the United Kingdom 🇬🇧 on 12 September 2019*

I'd read that this bottle was good for keeping sparkling water in and they were right. I've had no issues with leaking and it is really good for sparkling water.

### ⭐⭐⭐⭐⭐ 







  
  
    Ignore cheaper options. This works!
  

*by S***M on Reviewed in the United Kingdom 🇬🇧 on 27 March 2019*

I got a good deal on 2 bottles. Went for the 750ml as it still fits in my pouch on my office backpack. It does all FLSK say it does! Great product.
