These are not considered as “sharps”1, but my recommendation is to carry them in a carrying case (something like this item from Nisi):
I would not risk it in checked baggage unless you put them in a Pelican case or something extremely robust.
Source – sadly, first hand experience with checked in photography equipment, even though it was in its original box AND surrounded by packing foam.
1 – as long as you don’t run into the same TSA agent as this poor fellow.
