But you didn’t say that, OP.
You said this are my M&S Grenson copies, aren’t they good, so people, and I did too, said no, they aren’t good copies
What I meant to add, but didn’t is that Grenson is a small company and it’s really not nice to brag about copies or their things.
The same reason I don’t buy or recommend dupes or perfumes, it rips off someone’s work.
