There is a Rubik's Cube Zhu Xiao in Dalian. I bought a Rubik's cube from him. I think he has many varieties, all of which are of high quality, and the sellers are also very real and beautiful. You can contact him. He has a Taobao shop:

They are all from Dalian. You can contact him to trade in the same city, which can save some postage! Ha ha!

I wish you success in buying the Rubik's Cube you want. Have fun!
