The invention relates to a packaging system for medical consumables, in particular test elements. The packaging system comprises an outer packaging, which accommodates a first desiccant supply, and a magazine with an unused test element supply. In the closed state of the outer packaging, the first desiccant supply of the outer packaging acts on the interior of the magazine via a connection that permits water vapor diffusion. In exemplary embodiments, the magazine includes a second desiccant supply. The communication of water vapor between the magazine and outer package reduces the load on the desiccant supply in the magazine.
