Ordered new ones from Leebmann.de

These new ones were broken out of the box.
Original BMW, but they just seem super brittle.
Right side had a crack at the middle section almost halfway, while the left one was cracked only slightly at one side.
Going to return these ones, but afraid I will only get another 2 that is equally bad.

Didn't BMW redo these in a different plastic the original version?

Maybe I got some old-new stock??!!

Is there a way to see when the part was made looking at the BMW p/n sticker?
