The block body includes magnet-holding portions where the disk magnets are arranged along the coupling sections and held in a circumferentially rotatable manner. Length of at least one side of the block body is equal to or longer than 30 millimeters and shorter than 40 millimeters. Only the coupling sections are provided with labels indicative of being capable of coupling to a coupling target. In the coupling sections, stepped portions are formed so that at least part of an outer-edge portion of each coupling section protrudes. ## Claims ### Claim 1 A magnetic block toy that is magnetically coupled to a coupling target, the magnetic block toy comprising: a block body having, on outer surfaces thereof, a coupling section that is a plane section capable of magnetically coupling to the coupling target and a non-coupling section that is a plane section incapable of magnetically coupling to the coupling target; and a disk magnet provided inside the coupling section in the block body and having a north-pole portion and a south-pole portion aligned along a circumferential direction thereof, wherein the block body includes a magnet-holding portion in which the disk magnet is arranged along the coupling section and held in a circumferentially rotatable manner, length of at least one side of the block body is equal to or longer than 30 millimeters and shorter than 40 millimeters, only the coupling section out of the coupling section and the non-coupling section is provided with a predetermined label indicative of being capable of coupling to the coupling target, in the coupling section, a stepped portion is formed so that at least part of an outer-edge portion of the coupling section protrudes. ### Claim 2 (depends on 1) The magnetic block toy according to claim 1, wherein the predetermined label includes a figure including a figure schematically illustrating a projecting shape of a fitting structure in which the projecting shape fits into a recessed shape, and formed by painting. ### Claim 3 (depends on 2) The magnetic block toy according to claim 2, further includes a yoke adjacent to an inner side of the block body with respect to the disk magnet, and the block body consists of one box member and one lid member. ### Claim 4 (depends on 3) The magnetic block toy according to claim 3, wherein the part of the stepped portion is formed from the lid member jutting out between the lid member and the box member at the outer surface. ### Claim 5 (depends on 2) The magnetic block toy according to claim 2, comprising: a first coupling section and a second coupling section as the coupling section, the first coupling section being provided on the outer surface on one side of a predetermined direction, the second coupling section being provided on the outer surface on the other side in the predetermined direction;
