Only sold in white. Used a screw-spring mechanism. These cubes were often used by beginners because of its ability not to overshoot or lockup as much as the Eastsheen. The screw/spring structure provided good corner cutting and stability.
Type E cubes are known as Diansheng (or DS) cubes. Out of the box they were quite bad, but after lubing with silicone they became much better. One problem was that they were somewhat prone to locking up, due to the very cubic cubies. There are two types of DS cubes, no.222 and no.333. Rather than stickers, the Diansheng no.333 has the colors painted onto the sides of the cube. The color scheme is a mirrored version of the Western color scheme. The no.222 has regular stickers. Both of the painted and stickered types have different cubies. Because of their very light weight, and very loose, smooth turning; DS 3x3x3's were often used in One-Handed cubing.
