MEOWCAFE K-Keep A5 Wide Binder, 1.5 Inch, Compact Kpop Photocard With 25 A5 Slim 4 Pocket Page and 2 Backboards, Comprehensive Beginner (ICY Blue)

could you show us the binder or the pages you own? you might already know all of this but just in case, those 56 x 87 sleeves are basically the standard ones that would fit any page, the 61 x 91 sleeves are used as double sleeves, to make sure the photocard isn’t moving around within the page! edit: adding my set up i use this binder with similar a5 slim pages, also those 56 sized sleeves!https://a.co/d/0aeUEt8f
