### ⭐⭐⭐⭐⭐ Great flask!!
*by K***T on September 6, 2025*

### ⭐⭐⭐⭐⭐ Good flask
*by C***E on February 5, 2026*

Great flask for the beach

### ⭐⭐⭐⭐⭐ One tough cookie!
*by D***G on November 23, 2025*

Driving down the road at 55 mph I hear a thump. Looking in my rear view mirror I see something tumbling down the middle of the road behind me. Suddenly I remember setting my flask on top of my car before leaving home. I turn around to retrieve the flask overjoyed to discover that it only suffered a bit of stuffing on the screw cap. This thing really is shatter resistant! Perfect size for those 3 -4 mile walks. Fits nicely in a pocket.
