Hi Minnie and congrats on getting Yuu, he is wonderful, I've drooled over his pics many times.
Mary gave you Jpopdolls website there. She also sells on ebay and her username is designersndolls03
I've bought from her twice and found her great to deal with. She has a wonderful selection of wigs, and I particularly like her own brand ones which are made from synthetic mohair and are so gorgeous and soft. Breffni's lovely red wig is Jpops own Kana Firefly. It's size 8-9 and fits Breff perfectly, which is great as some 8-9 wigs can be tight on her - she has a huge head.
She charges $6 shipping from US to Ireland, which is not bad at all. I'm sure there's a shipping discount for multiple items. She also sells the Monique Gold Collection, which are synthetic mohair as well.
Listen to me giving BJD advice - not so long ago I was clueless
