Absolutely ingenious, extremely encouraging and so necessary. How could it have taken so long for this to happen to us? Stainless steel flask and bangle married to each other! Measuring 3.5" in diameter across the entire bangle but then the inside diameter is 2.5" Its a little tighter of a squeeze but worth it. 1 1/2" wide and hollow, with screw on cap and a dangling safety chain. Monogrammed on the inside of the bangle. Holds 3 fluid oz. Also available in gold plated. By Cynthia Rowley.
