This Stemless Wine Cup in Island Bloom comes with a spill-resistant and shatterproof lid, which seals tightly with a rubber gasket and can be covered with the sliding closure to minimize spilling. The cup also comes with a non-slip silicone base and a matching reusable BPA-free polypropylene straw. The 14oz Stemless Wine Cup and included accessories are all dishwasher safe. Each Signature Swig Life™ Stemless Wine Cup keeps drinks cold up to 9 hours and hot up to 3, thanks to its double-walled, vacuum-sealed and copper-coated insulation. So they’re perfect for enjoying chilled wine by the pool on a hot summer day or hot coffee in the mornings.
