Much better than basic cardboard - TruGlo 100 Yard Target, 12in. x 12in.

The peel and stick feature of these targets is great. I purchased two different styles and affixed 2 of each to a standard cardboard target along with 4 smaller targets. We had plenty to shout at for a few hours. The splatter feature made picking up hits through binoculars a lot easier. I should have purchased these a lot sooner!
