Also called 'GuoYou', Type D cubes ship fully assembled and stickered. The color scheme varies, but generally they are stickered in either the Japanese color scheme or a mirrored version of the Western color scheme. The original stickers are generally not as robust as most vinyl stickers, which is why Cube4You ships a set of better stickers with each cube. Recent Type D orders came stickered with nicer vinyl stickers(similar to storebought stickers) in the Western color scheme. Type D cubes rarely pop, unlike Type A cubes. They also are decent at cutting corners. The argument as to which is better for speedcubing, however, has not been settled. Some people recommend replacing the Type D core with a Type A core. It is also recommended to try a hybrid of this cube with Type Ccubies.
