Good quality sheets, easily fit into the terminals of a Denon X2100, you must force a little all the same, fortunately, otherwise it will not hold up ... The contact is perfect. Supplied in bag, for cons I have not found that they were specially lined for the person as the previous comment. There are 2 screws, one for the stripped portion to make contact right and the other to hold the cable in place, that's fine. I recommend !!
