Our Story

Dear Fellow Collector,

     Welcome to our webstore with inventory matching that of our eBay store, but at lower prices. 

      I have been a collector my entire life; an unfortunate child of the 'junk era'.  While the era may be different, the childhood stories are quite similar.  I can remember working around the house for my allowance and working odd jobs in the neighborhood all so that I could muster up a few dollars.  I'd ride my bike down to the local convenience store, pick out a pack or two or the year's finest baseball cards and rip into them.  The feel of the cards in your hands, touched first by you, was a surreal feeling and a lasting memory.  The story is the same no matter what decade or era you grew up in.  We all remember our childhood memories of the hard work it would take to scrap together enough money to spend it on ripping open a fresh pack of cards. The memories stay with us, which is why we still collect these simple pieces of cardboard and why they continue to hold value decades later.

     Diamond Cardboard has been selling cards on eBay since 2013 and have continued to keep an impeccable track record with 100% feedback and continued customer retention.  We have fair and reasonable prices, ship quickly, and leave our customers satisfied.  If they aren't fully satisfied, we offer returns and full refunds.  Simple as that.  At Diamond Cardboard, we want your experience to be smooth, quick and foremost enjoyable.
