The final polish I bought from Models Own Beetlejuice collection is Golden Green, this is such an unusual polish, I haven't owned anything like it before. As the name suggests, this is a duochrome polish which flashes gold and green. I found the formula more runny and streaky than Purple Blue and Aqua Violet.
However, this is such a stunning colour, observe:
The other two polishes which I didn't get are Pinky Brown and Emerald Black. Pinky Brown has been out of stock for a while so once that one comes back I hope to grab that one too. Emerald Black didn't really excite me so I skipped that one.
