I have bought 3 wigs from local stores and they also costed between 12 and 15 €, just like this Killua wig. Those other wigs were REALLY bad quality so when I unpacked my new wig I was more than happy to see that the quality is great! Also, the product looks just like pictured. :D
My order arrived about 4 days later than the max. delivery time so I got a bit worried that it had gotten lost somewhere. But my only problem with this wig is that I don't know how to hide my own hair. The cap fits perfectly when I put my hair in a low ponytail down my back. I just have extremely long and thick hair so it's difficult how tuck it away when the cap size is so snug.
My pictures are not cosplaying pictures, but i wanted to show how it looks on a real head ^__^. The wig is completely unstyled and uncut. Also on these pictures i have my own hair in a visible ponytail in the back.
