I've been buying from them for quite a while already and their products (wigs and cosplays) are really well made. And they offer a 5% off coupon for when you send photos back of you wearing their cosplays (which are exclusively used for their blog's photo gallery).
The only downsides I have with them is the communication process (sometimes, can take days to reply) and I don't think they don't allow exclusion of some parts of a cosplay since one time I asked if they could excluse the white dress shirt for my cosplay but still was included in my order. ''orz
Also, it's advisable not to order from them around Late December-February because of Chinese New Year holidays. The shop closes and takes a two-week break. So, if you need a cosplay around that time, do it early.
