Bazi knee pads are good.
1. The eight-figure knee pad has a good fixation effect and is suitable for sports. However, the four-grip knee pad has a poor fixation effect and is not suitable for sports.
2. The eight-figure knee pads can also be worn when sleeping. They are very strong and will not fall off easily. However, the four-grip knee pads cannot be worn when sleeping because they are not firm and will fall off easily.
