The transparent cover is made of solid, yet soft plastic. The black package that contains the drill is rubbery and very stable. Falls are not an issue. The drills are stuck in a small "block", which can be moved by pressing on the lower side facing upwards / forwards. Thus opens up to one of the transparent lid and the drill stand up and can be easily removed. Additional property the "drill-box" opened by itself.
It should be noted that a slot is present at the level of the drill diameter in the transparent cover. Thus, the drills are always well-aired. That with the ventilation is just a guess on my part. ;-) Only negative point that strikes me is an indication of the diameter of the holder blurred slightly when driving over it with a finger. Because among other things, the diameter is also available on every drill, which is not quite as bad.
Conclusion: Very good drill in a very good box.
