i just bought a 4x4 and 5x5 cubes from the Rubiks online store and they come packed in a transparent container (like for exhibition). I would like to ask how are those boxes called? Its that kind of boxes you can open and close as many times as you want. However, they are far easier to open than closing them again. I cant close mine so would like to search for a tutorial but i cant since i dont know how are these box called. Could anybody please tell me?
