Serious company, fast shipping with tracking number, slow response to emails.
I am buying from them by few years and I have no problems with their products, are responsible but are hard to answer emails.
The funny thing is, whatever the price that you buy from the store, the maximum stated in the custom declaration is aprox 19.99$, take this in mind if you have problems with customs.
The best is the proxy service to buy at auctions of Japan.
