About us

WE ARE passionate about sports card collecting. Here at Diamond Cardboard, we've been doing it all our lives. We started selling cards on eBay in 2013, and we've proudly maintained a 100% feedback rating. But for us, it's not just about the cards or their value—it's about the love of the game and the love of collecting. Growing up, there was nothing like tearing open a fresh pack of baseball cards, hoping to find your favorite player or that one rare card that would light up your day. That excitement is something we carry with us into our business every day.

Our goal is simple: to give you that same joy and excitement we had as kids, whether you're hunting for the final card to complete your set or just reliving memories. We offer fair prices and quick shipping, and if you're not happy with you're purchase, we'll do our best to make it right. At Diamond Cardboard, we want every step of your experience to be smooth, fast, and most importantly, fun!
