These are cotton patches - not synthetic - Hoppe's 9 Gun Cleaning Patches

The product description does not specify the patch material. One of the questions asked if they are cotton or synthetic; the answer given was 'synthetic'. That's exactly what I needed, but unfortunately THE ITEM I RECEIVED WAS COTTON, which was printed directly on the front of the packaging. The lack of a proper material description was why I removed one star from the product rating.
