Because the Klean Kanteen Steel Pints are designed to replace plastic and paper cups, they really need to travel with you...and the pint rings make that super easy. Your empty pint can be clipped to almost anything or just swung from your finger. Pick a color, outfit your pint and see how many single-use cups you can refuse in a week, a month, or a year. You will be doing your part, and showing everyone who sees your sweet pint how they can too. Available in Dark Green, Orange, Blue, and Bright Green. Sold individually, or as a 4 pack.
