Booklet cards are hot for sports cards collectors! They are often extra thick with jersey patches and/or autographs. These cards can be stored in a closed format in a hinged or slider box, but most collectors like to store their booklets in the open position to get the full presentation. BCW offers sleeves, toploaders, and bags to enclose the toploaders (the bags can also enclose a magnetic booklet card holder). The supplies listed below are available for booklets in horizontal and vertical formats.
