"Just replace the metal lid with this cool new Cuppow sipping lid to transform an old-fashioned wide mouth canning jar into a uniquely interesting and inexpensive travel mug. It's an ingenious and funny alternative to the typical slick and expensive travel mug, but until they invent a canning jar travel mug insulated sleeve, you'll need to be careful with hot coffee and tea."
THIS IS RIDICULOUS. you can get a ok thermos for $9 and this thing looks like cheap plastic. anyway.. this thing is actually real: http://www.cuppow.com/
