1. A set of panels comprising a first panel with a first main plane and a second panel with a second main plane,
wherein the first main plane is essentially perpendicular to the second main plane in a locked position of the first and the second panel and a junction plane is extending between the first main plane and the second main plane,
wherein the junction plane is in the locked position extending from an inner corner to an outer corner of the first and the second panel,
wherein the first and the second panel comprise a mechanical locking device which is configured for locking a first junction plane surface of the first panel to a second junction plane surface of the second panel at the junction plane,
wherein the first junction plane surface and the second junction plane surface extend along the junction plane,
wherein the mechanical locking device comprises a rod-shaped element at one of the first or second panel intersecting the junction plane and configured to cooperate with an element groove at the other one of the first or second panel for locking the first and the second panel in a first direction which is perpendicular to the first main plane,
wherein:
the one of the first or second panel comprises a locking groove and the other one of the first or second panel comprises a locking part configured to be inserted into the locking groove, wherein the locking groove is a fully blind hole with a bottom surface facing an opening of the locking groove,
the locking part comprises a locking surface configured to cooperate with a locking surface of the locking groove to lock the first and the second panel in a second direction,
the locking part is of a cylindrical shape, and
the cylindrical locking part is configured to be displaceable in an axial direction of the cylindrical locking part during a locking of the first panel to the second panel,
wherein the rod-shaped element protrudes from and intersects the first or second panel at a first surface of the first or second panel, and the locking groove is recessed from and extends to the first surface of the first or second panel.
