Our 12 oz stainless steel insulated mug keeps coffee hot for up to six hours — cocoa, tea, and toddies, too. It's refillable, reusable, and sized for the perfect cup. The closeable press-in lid tames splashes and is straw compatible. The soft touch exterior provides a comfortable hold. The TempShield double-wall vacuum insulation protects temperature for hours. Made with 18/8 pro-grade stainless steel for durability, pure taste, and no flavor transfer. This product is BPA-free. It's not suitable for use on a stove, in a microwave, or freezer. For safety, keep hot liquids out of the reach of children. For cleaning, hand wash with warm, soapy water. The closeable press-in lid is top rack dishwasher safe only. Avoid cleansers with bleach or chlorine. Wash before first use. This unisex mug is available in various sizes and colors, including the OS size and Birch color.
