PRO-Fit Edge inner card sleeves are designed for standard ("Magic") sized cards. The specially designed black border gives cards a uniform look while framing the artwork of the card. These inner sleeves fit tightly around the card to give it an extra interior layer of protection. These standard sized PRO-Fits can be used in conjunction with Ultra PRO's 35pt ONE-Touch magnetic card holder, which is especially recommended if the card is expected to be taken in and out of the holder frequently. Made from ultra clear, archival-safe and acid-free polypropylene film. Only use with cards with rounded corners. Do not use with sharp-angled sports cards as the tight fit may damage the corners. 100 sleeves per pack.
