This is not a UK company, even though there's a UK address on their website. The fine print tells you that the shipping and return address is another country! China.
Check sizes. What looked like normal pendants on the website are too small for a doll! It's all metric so Americans will probably need a ruler.
If you want to send anything back, it will cost you at least $16... making it not really worth it.
BTW - All this "credibility" stuff on this site... I'm not sharing my personal info for a review.
