The Pro-Mold Magnetic Trading Card Holder features a gold magnet that provides a super-strong enclosure, which allows the holder to stay closed when dropped while it's still easy enough to open up and put a trading card in it. The hobby's first, non-graded, trading card holder that will hold a penny sleeve! Ideal for those cards that you are worried may scratch like Panini Prizm, or Topps and Bowman Chrome cards. This holder provides 5 years+ of UV protection to prevent the card and autograph from fading, and Pro-Mold magnetic holders are the only ones that have UV certification.
