42 Utility Towel
Never be without your Towel again!
Ford had one. Zaphod had one. Even Arthur had one. And now you can join the ranks of some of the best intergalactic hitchhikers ever. It's black and has the number 42 on it. Never be without your Towel again.
The Towel is perhaps the most important invention of whatever century it was invented in. The Towel is the most massively useful tool to take with you on your trips throughout the universe. It is handy for oh so many reasons: you can sleep on it, rub food and sauces on it for later consumption, use it to signal for help, wrap it around your head to avoid the gaze of the Ravenous Bugbladder Beast of Traal, or to dry off. And most importantly, strags (non-hitchhikers) will assume if you know where your towel is you are also in possession of quite a number of other common items like a toothbrush or a space suit (which means they are more apt to lend you said items if you ask to "borrow" them).
Our Towel is black, rectangular, and made of velour. It is based on the award-winning design of the Anti-Flatulent Fighting Towels of Flogulon Beta, with a little clip in the corner to attach it to things. It measures 16" X 25" and has the number 42 imprinted on it for some random reason (apparently the printer had a special affinity for the product of 6 and 7). The printing is done using a tone on tone effect, using a glossy clear ink over the black towel for a nice subtle effect. But seriously, you need this Towel. Because if you have one, everyone will look at you and say, "There's a frood who really knows where his towel is," which is perhaps one of the nicest things someone can say about you.
And don't forget: May 25th is officially Towel Day. It is a tribute to a mostly harmless author named Douglas Adams.
