Slightly oversized for easy insertion and removal of sports trading cards. Used by Professional Sports Authenticator (PSA) and most PSA dealers for card submissions. Also works great for the larger -sized, pre-1957 trading cards. Not only are these card holders ideal for personal use, but they are also a must-have for collectors looking to submit their cards for professional grading. The PSA submission size ensures compatibility with the grading process, making it a breeze to prepare your cards for submission.
