Welcome to Diamond Cardboard, LLC.

We have developed and maintained a niche for selling quality baseball cards at very reasonable prices, all while bringing the utmost service and satisfaction to our customers.  

What started on eBay in 2013, has now grown into Diamond Cardboard, LLC.  
With this change, we are now establishing our own web store with identical inventory,
just at better prices than on our eBay storefront.

We believe that when we save, you should too!  Take a look around,
you should find something you like and at a price you like, too!
