Okay, these bases are seriously huge and honestly a game-changer if you're tired of those crazy collisions during games. Each one measures 16x16 inches with a 1/4 inch thickness, so there's plenty of room for both runners and defensive players. The textured surface is smart too - gives you better grip so you're less likely to slip. They're made from durable vinyl that can handle being left outside overnight (we've all forgotten to bring equipment in, right?) and they work great indoors or out. The set comes with all four numbered bases plus home plate, and the numbers are extra-large so you can actually see them while you're running. If you're organizing games with kids or even adults who get a bit too competitive, these help make everything safer while still keeping it fun. They're not those flimsy bases that move around either - these stay put during play. Perfect for schools, leagues, or just backyard games where you want something that'll last more than one season!
