These are storage boxes for five Nikon DSLR lenses:

• 28mm f1.8
• 85mm f1.8
• 105mm f2.8
• 10-24mm f3.5-4.5
• 55-200mm f4-5.6

Essentially, they are boxes with cutouts of the silhouettes of the lens to secure them. There are a couple of millimeters of margin between the lens and the walls.

The boxes are printed with low strength settings to preserve material. These boxes are not meant to protect the lenses during transit, just to more securely keep them in storage.
