Oblo is a 3D didactic puzzle for children. In order to progress from one level to the next, users must find the correct position for each piece that enables it to be removed. Following the principle of the key and keyhole, disassembly and reassembly of the toy is made possible. The container consists of four equal parts, one of which is the lid. The spherical pieces inside the container can be rotated 360 degrees, and the colors emphasize the different diameters of the layers. Oblo was designed to aid in the development of fine motor skills in preschool children.
