New at Peach Riot collection, need advice

Hello! I'm looking to collect some Peach Riot figures. I live in Brazil, so in terms of prices, it would be much better if I could buy from Pop Mart's official store on AliExpress. The thing is they're not in stock since the series I'm looking for are not that recent. I saw other stores selling these figures for a reasonable price, and the reviews are good, but I'm not sure if they're genuine. Does anyone know if it's common for resellers to have fake figures like other Pop Mart's characters?

I already collect Molly and have one CryBaby, but they were bought from the website. I have a friend who can send it to me from the US, but it's a lot more expensive since Brazilian taxes are crazy right now.
