The Easy Fill Wide Mouth Flask 0.23L Hammertone Green

The The Easy-Fill Wide Mouth Flask 0.23L brand's signature product Stanley is the flask that never lets you fall – unless, of course, it's empty.

Its retro look, portable size and slim design mean it fits in anywhere. The wide opening makes it easy to fill (no funnel required), and the stainless steel construction with a leak-proof stopper makes it even more durable.
