In collaboration with artist Ashley Woodson Bailey, Corkcicle brings her love of flowers and signature "florography" to their classic tumblers for a beautiful sipping experience. Crafted from stainless steel with proprietary triple insulation, the tumblers provide superior insulation, keeping cold drinks chilled for over 9 hours (more for iced drinks) or hot for 3 hours. All pieces have slip-proof silicone bottoms and a crystal clear sliding, spill-resistant lid.
