Take it with you to work, school, on trips, while you do errands ... \n\n\nExtra-wide mouth -- means you can set your sieve directly over it, sift your matcha, add hot water, and froth it up right in the tumbler. Close the lid and off you go. \n\n\nTapered thin lip -- mimics a wine glass to deliver matcha directly to your palate while sitting comfortably on your mouth.\n\n\nFits in most car cup holders.\n\n\nCeramic interior -- your matcha should taste how you intended. Unlike stainless steel, a ceramic interior keeps your brew free of odors, oils, and metallic “old penny” tasting notes.\n\n\nHeat-lock double wall vacuum -- 304 18/8 insulated stainless steel retains heat for 12 hours and stays cold for 24 hours.\n\n\nLeak-proof seal -- A quick, 270° twist locks the lid to eliminate liquid mishaps. Guaranteed.\n\n\nMaterials -- 18/8 stainless steel, BPA-free plastic and steel lid, inner ceramic coating.\n\n\nSizes &amp; Dimensions: 12oz: 158 mm tall w/ lid, 135 mm tall w/o lid\n\n\nCapacity: 12 ounces\n\n\nIncludes stainless steel splash guard.\n\n\nMade by the fine folks at Fellow, who also make the gorgeous Stagg Kettle for us. \n\n\nCare: Not dishwasher safe.
