Yeah, they're soooooo purdy! POP stands for Portrait Of Pirates. You can check out the Sanji one here (http://www.hlj.com/product/MEG71016). They're also hella hard to get hold of. Luffy, Zoro, and Nami were Series 1, Sanji, Usopp and Chopper (sold together), and Robin were Series 2, Tashigi, Vivi, and Ace were Series 3, and Smoker, Bellemere, and a second version of Nami were Series 4. Series 4 is still around, you can still pick up the reprints in places like the shop linked above, but the others are mostly only available through eBay, and being collector's items means that the rarer ones are often over £100. *is sad* I've managed to get most of them at a decent price, but Luffy, Zoro, Sanji, and Ace are waaaaaaaaaay beyond my budget.
