Looks just like the one I got at Walgreen's for $6.00, brand was Detailer's Choice.
I have purchased them at Walgreen's, Advance Auto, Harley Davidson etc and they are basically the same mitt. It is genuine sheepskin, leather mitt on the inside. I've paid anywhere from $5 -7 for them all.
I have been to a few specialty car detailing boutiques that sell sheepskin mitts (In Cleveland, Chicago and Philly) and they all look the same.
I am tempted to buy one from Griot's (the one with the rubber glove inside) just to see if there's any difference with the mitt. But I just can't bring myself to spend the extra $ when I could spend it on something else, like another jar of S100!
