That seems pretty reasonable to me too - this seems like a good time to try to make up tabs on proportions of these cards. This bright green colour seems to be standard (see Julio's shop), and I have seen a few solid pink ones
like this one.
And then I have seen quite a few that have some of the "Honeydukes" bright pink and green logo.
Has anyone looked into numbers of these because I think I have only seen 2 solid pink ones - and both had creases in - I think it's possible that the pink one I have seen twice is the same one but I'll have to ask the seller... anyone got any ideas?
