Panels comprising a mechanical locking device and an assembled product comprising the panels

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 and the second panel are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel at a junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane, wherein:

• the first edge comprises an edge tongue that extends from the junction plane;
• the second edge comprises an edge groove at the junction plane, wherein the edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in a first direction which is parallel to the junction plane;
• the edge tongue comprises a tongue groove;
• the edge groove comprises a flexible tongue arranged in an insertion groove, said flexible tongue is configured to cooperate with the tongue groove for locking together the first and the second edges in a second direction which is perpendicular to the junction plane;
• the first edge comprises a first edge surface which is parallel to the junction plane, and the second edge comprises a second edge surface which is parallel to the junction plane, wherein the first edge surface is configured to cooperate with the second edge surface;
• and
• the first edge surface or the second edge surface comprises a recess.
