Help & Info

Card quality and conditions

Unless stated otherwise in the product description, all cards are near mint or better and meet the following conditions: all cards listed in our shop have never been played with. All cards are immediately sleeved after opening. We are the same as any other shop selling single cards. Please do not purchase with the expectation of achieving a definite "PSA 10" or a "Beckett Black Label" after grading, there is a possibility you will achieve those grades, however all cards are prone to imperfections in the printing process... that is out of our control.
