Any idea when the Models Own crackle polishes are due to be released, Lou? I just saw pics of them online too (in the bottle, not on nails, unfortunately, but they do have different colours to others). I believe Barry M's new crackle colours come out some time this month, so I'm going to look out for them. Boots 17 apparently have some in silver and gold, so I shall definitely be checking those out.
I do have a few Models Own polishes, but I think the last one of those I bought was just before Christmas. I'm hoping there's not a problem with those.
