Wrap your mask in a towel and away you go. If you have anything delicate, put it in a tough case or take it carry on.
To me, these things seem like something people should figure out themselves. If you can't figure out that something could be damaged in flight and take measures to prevent it, well you will learn a very valuable lesson when you reach your destination and need to buy something new or just miss out.
that's the first I've ever heard of that, but I place my mask in it's case, and luckily my luggage doesn't allow for damage if packed properly.
