Who said vacuuming was just for floors? We've put the Suction Seal of Approval on this Tahoe Vacuum Tumbler. Made from 304 Grade 18/8 Stainless Steel, the inside is lined with copper and vacuum sealed for ultimate performance. We love a good colored-powder coating (just not on our baseboards) and this tumbler comes with just that. Work with our experts to decide how you'd like to imprint your logo—it'll be so pristine, clients will want to eat off of it. Or rather, drink from it. Dyson's got nothin' on us.
