Renewed and revived! Try not to change popular designs as much as possible! However, we have updated it to make it look a little better. The new [FORCE3] uses two types of ore. By alternating the ore and natural stone that emit negative ions used in the conventional FORCE series, we have kept the appearance as unchanged as possible, and the amount of negative ions emitted has decreased slightly, but we have renewed it by ensuring that the amount of emitted is equivalent to the professional model.
