Abstract: A kit including a packaging and an injection device is described. The injection device defines a positioning recess. The packaging includes a channel extending longitudinally to accommodate the injection device. The channel includes a first longitudinal wall, a second longitudinal wall opposing the first longitudinal wall, and a base wall extending between the first longitudinal wall and the second longitudinal wall. The packaging also includes a first handling recess defined by the first longitudinal wall and a second handling recess defined by the second longitudinal wall. The packaging also includes a positioning rib protruding from the base wall into the channel for insertion into the positioning recess of the injection device.
