Pocket type wallet comprising a first wall and a second wall having a substantially rectangular longitudinal development and the same height comprised between 110 mm and 130 mm, and being reciprocally attached to each other, wherein each of said walls (11, 12) is made with a material having a thickness comprised between 0.5 mm and 1.5 mm, wherein said second wall has a width which is about half that of said first wall and is sewn at the front on the latter by means of a main stitch which develops along three sides of the perimeter of said second wall, leaving one of its bigger sides free, whereby the back surface of said second wall and the front surface of said first wall define a main pocket, wherein said walls (11, 12) joined together are suitable to be bent longitudinally on themselves along a main bending axis, to define four flaps (13a, 13b, 13c, 13d) rectangular in shape and all having substantially the same length comprised between 87 mm and 110 mm, wherein said four flaps (13a, 13b, 13c, 13d) identify respective front rectangular surfaces (15a, 15b, 15c, 15d), which when the wallet is in its maximum open condition are coplanar with respect to each other, whereas, in the closed condition pairs of said adjacent front surfaces (15a-15d) face each other, wherein two main flaps (13a, 13b), included in said four flaps (13a, 13b, 13c, 13d) are positioned on opposite sides with respect to said main bending axis and each having one of said rectangular surfaces (15a, 15b), wherein at least one main containing element (26a, 26b) is attached on said one of said rectangular surfaces (15a, 15b) of each of said two main flaps (13a, 13b), so that each main containing element (26a, 26b) defines at least a first pocket having shape and sizes such as to contain at least a one card having a rectangular development, with a short side and a long side with standard sizes, and wherein each main containing element (26a, 26b) has a surface that is equal to or less than half of each one of said rectangular surfaces (15a, 15b) of each of said two main flaps (13a, 13b), wherein said first wall comprises a first secondary flap of said four flaps (13a, 13b, 13c, 13d), positioned adjacent to a first one of said main flaps (13a, 13b), and wherein said first secondary flap can be bent over said one of said main flaps adjacent to it along a first secondary bending axis parallel to said main bending axis, wherein on one of said rectangular surfaces of said first secondary flap at least a first secondary containing element is attached which defines at least two second pockets each having sizes such as to contain a standard-sized card, wherein said first wall has sizes such as to also define a second secondary flap, included in said four flaps (13a, 13b, 13c, 13d), positioned adjacent to a second one of the main flaps (13a, 13b), on the opposite side to that where there is said first secondary flap, and that said second secondary flap can be bent over the main flap adjacent to it along a second secondary bending axis, parallel to said main bending axis, and wherein on one of said rectangular surfaces of said second secondary flap at least a second secondary containing element is attached, which defines at least two third pockets, each having sizes such as to contain a standard-sized card, wherein each main containing element (26a, 26b) is attached on the corresponding determinate rectangular surface (15a, 15b) of one of said two main flaps (13a, 13b) so as to be offset with respect to the main containing element (26a, 26b) adjacent to it, so that when said two main flaps (13a, 13b) are bent back one on the other along said main bending axis, in a closed position of said wallet, the main containing elements (26a, 26b) are at least in coplanar pairs and therefore not overlapping each other, and wherein said first and second secondary containing elements (26c, 26d) are positioned on said secondary flaps (13c, 13d) so that, when said secondary flaps (13c, 13d) are bent over said main flaps (13a, 13b) along said secondary bending axes (P2, P3), when the wallet is in said closed position, said first and second secondary containing elements (26c, 26d) are each adjacent to and not overlapping the corresponding main containing element (26a, 26b).
