The Zeiss Milvus Transport Case is designed to accommodate six Zeiss lens inlays. The case comes with a foam insert that has six openings for placing your separately purchased inlays. The case is waterproof, thanks to the neoprene O-ring, which prevents water from seeping in. This case has a latch closure to keep the lid tightly closed and your stored lenses secure. Both sides of the case have openings for user-supplied padlocks. The top carry handle makes it convenient for you to travel with this shock- and impact-resistant case.
