From what I can tell, Kleshna don't make the paper poppies at all...?
In fact, that article you linked to is pure Daily Mail, in that it is what it doesn't say that is significant. From the headline and subheads, you would think - as I briefly did - that the Kleshna poppies were in some way comparable, either in terms of the numbers sold, or type.
But that's not the case: Kleshna make small quantities of jewelled and "designer" poppies, in small numbers, and have nothing to do with the paper poppy production.
It's a deliberately misleading article, in my view, and I'm somewhat surprised at an Urbanite quoting such a piece of drivel!
