If you’re still drinking lukewarm liquids... what are you even doing? Amazon’s offering big discounts on several Simple Modern drinking vessels in all shapes, sizes and mouth types. Options include an insulated coffee mug, a water bottle, a tumbler, food jars, and accessories. There’s a few with sports logos, too, if you’re into that sort of thing.
These prices are only good today or until sold out, so pick one up before this sale goes away. Of course there are over a dozen options, and while I have included a few here, you should probably visit the main page for all of your options.
