That's not so much a seam split as a crack in the laminate caused by a forceful drop. Really, no packaging can prevent that.
But it is really easy to fix, I do it all the time. Take a decent artists maker and run it over the crack. Make sure it is the same color - black is really easy. Usually the ink is enough to fix it. If not, run a small amount of good, clear glue over it with your finger. Smooth over any excess so it is not noticeable.
Seam splits have been around for decades. Most are easy to fix, with a set of markers and glue. Even a true, right through split can be fixed to the point where it is hardly noticeable.
