    • A set comprising a first panel (1) with a first main plane, a second panel (2) with a second main plane and a mechanical locking device configured for locking the first panel (1) to the second panel (2) is described. The first panel (1) comprises a first edge (11) and a first panel surface (12) and the second panel (2) comprises a second edge (21) and a second panel surface (22). The first main plane is arranged essentially perpendicular to the second main plane in a locked position of the first panel and the second panel. The mechanical locking device comprises a first tongue (3) and a groove surface (5) at the first panel surface (12), and a locking groove (4) and an edge surface (6) at the second edge (21). The first tongue (3) comprises a first locking surface (31), the locking groove (4) comprises a second locking surface (41), the first locking surface (31) is configured to interact with the second locking surface (41) in the locked position, wherein the first tongue (3) and/or the locking groove (4) is/are flexible for facilitating locking of the first panel to the second panel. A longitudinal axis (34) of the first tongue (3) extends at a first angle (α) from the first main plane, the groove surface (5) extends at a second angle (β) from the first main plane, the second locking surface (41) extends at a third angle (γ) from the second main plane, the edge surface (6) extends at a fourth angle (δ) from the second main plane, and the first angle (α) is ≥ the second angle (β) and/or the third angle (γ) is ≤ the fourth angle (δ).
