Cubing Classroom Meilong 7x7 carries the Meilong formula up to seven layers at 66 mm and 182 g. Frosted stickerless surfaces give a dry, secure grip that suits the constant regripping big cubes demand. Colour separation between faces stays sharp, which helps during centre building on crowded layers. Screws under the centre caps allow basic tension tuning with a screwdriver, and instructions come included in the package.
