The mylar based Baader can have some pinholes in the coating, if we're talking about say 6 or so spread across the whole aperture, there's no serious risk.
More cosmetic than dangerous.
Baader do suggest, if you want, to touch-up the pinholes with a TEXTA.
If it's brand new, straight out the box, I would try to get a better replacement.

No try in it , if it's brand new , you have a right to have it replaced or a full refund if it's defective.
