A receptacle wall for use in or as part of a receptacle (2) for storing small objects removably by hand. Along a guide surface, with at least one finger of a hand, an object can be advanced and be taken out of the receptacle. Over the guide surface extends a lifting trajectory portion (5, 6; 15, 16; 75) along which height varies. An upwardly facing surface (9; 79) and the lifting trajectory portion (5, 6; 15, 16; 75) extend as far as an edge (10; 80) along which they meet. The upwardly facing surface (9; 79) runs up obliquely towards the edge (10; 80) for supporting a thumb of a hand of a user during the advancement of the object.
