3.5 months later the order has not arrived and most likely was never sent. At first, they answered the letters and said that the parcel was returned due to an error in the address, which is unlikely since all fields are filled in automatically and there have never been any problems. They promised to send it as soon as possible and for the last 2 months, they simply stopped responding.
And an important factor is that there is no talk of any handmade work from Japan. At best you will get a Chinese glass.
