We got 180 of these disposable cloths for about $11.50 on Amazon.com. They were a steal at two boxes (90 pre-moistened wipes in each box) for that price. These are so convenient; they are packaged like Wet-Naps (and, just like Wet-Naps, each cloth is 6 X 5 inches), so they are very portable. Stick them in your purse or tote bag, your pocket, your wallet, whatever. If you wear eyeglasses, you know how frequently the lenses need to be wiped off (you inadvertently touch a lense with greasy fingers, someone hugs you & their face touches your glasses, you get caught in the rain & need to rub the drops off of your lenses once you get inside; there are any number of reasons to have these cloths handy). These are also nice for wiping off your laptop (or desktop) computer screen. They get rid of the dust, lint, and whatever else you've managed to get on the screen. (They contain alcohol, so I even use them to wipe down the keyboard. And my cell phone). Again, these are so portable and convenient. Stick a few in your laptop bag; at some point, you'll be glad to have them handy.
