I can't compete with the copy. She is one funny copywriter, that's for sure. I love it so much, I have to share it. From the site:

Cool, flashy, silver thermal bags, another example of how something normally mundane and unnoticeable can be turned into something glamorous and beautiful. Great for carrying ice cream and drinks, hot or cold; padded, which means they are a good way to wrap fragile objects or a quick way to wrap a gift. Alternative uses: great for camping, to signal the search and rescue plane or blind the bear who is coming just a little too close for comfort. Photographers: wrap your assistants in them, they make great human reflectors. Office workers: use it to catch a few rays at your desk.
If that is not enough for you to want to buy a lifetime's supply, they are manufactured by a 70-year-old man who has been in business for 40 years.

Useful (insulated!) + attractive (silver!) + good back story (produced by a 70 year old man in the Shizuoka Prefecture for the past 40 years) = good conversation piece after you've unpacked the dessert you brought to the potluck. ($8 at Kiosk)
