Black Walnut Mug
Black Walnut Signature 18oz Swig mug. These mugs keep cold drinks cold up to 9 hours and hot up to 3 hours with its double-wall, vacuum-sealed copper coated insulation. The non-slip silicone base keeps your cups from tipping or making too much noise when you set them down. The powder-coated finish keeps the Swig looking fresh and is dishwasher safe!
