i am using his product description by adding one paragraph in begining and one in the end

self written 5 to 10 unique bullet points

So it is not really a paragraph you are adding, instead it is a set of bullets.

And the same set of bullets would be repeated on many product pages, so the would not be so unique? I mean many TV products would have the same/similar set of bullets,e.g.

Television Screen Size : nn Inches

I think it is likely that you are suffering from duplicate (and perhaps also thin) content.
