You could be right about the sherberts but the sun purpling is less of a clue to age in sunnier climes and I always feels that a lot of the just pre and post WW2 stuff is of dubious quality.
I also tend to agree with you about Ikea/Habitat quality, Poundland might be nearer the mark. I suspect Ivo means the sort of stuff that's stacked high at the wholesaler for every Tom, Dick and Harry Gifte Shoppe
