It may interest you to know that Amazon has begun shipping a cheap chinese imitation of the 3M product #07448. It is flimsly, performs poorly and wears out before the first job is finished. The cheap Amazon product doesn't even ship in the correct 3M box. Amazon ships the product in a white plastic sac. On the sack there is a white paper label proclaiming the product to be a "Scotch-brite.. 7448 set of 20"..
Thank you TCP Global for shipping the genuine 3M product. It performs admirably and is durable as expected.
