The majority of cards in the section are double fold (they have 3 panels with 2 fold lines), also referred to as '2 fold', or '3 fold' cards.
Each of the three sections here will take you to the same cards but they are arranged for you to select a card in one of three ways. Firstly, select by size which will show every aperture card available in each size regardless of whether it is plain, printed, foiled, multi aperture etc. Secondly by the shape of the aperture, and the third section is broken down by features such as plain, printed, foiled, embossed, single aperture, etc.
Either way will help you get speedily to the cards you require and once there, you will find handy links through to envelopes and clear bags if you should want them.
