Bobbi brown brushes

Bought a set of bobbi brown brushes at $280. stupid me got the cover stuck on the eyeshadow brush when i tried to open it. The plastic cap was so hard to pull it out. had to cut it and it spoilt my brush. I wonder if the cover is not able to fit back into the brush tip, then don't include it into the package. Else it must be able to fit back into the brush from the back. I haven't even use it yet and the cover got stuck. SO unfortunate.
