I did not understand the meaning of the can with well, but I think that it was good if there was a photo of Kang on the product case, so it was good to have it on the guide of the product. Although it is the main can, it is a hook to hang on the belt. The length is about 5 cm. Since the can is facing outward, it must pass under the belt. Since there is a length of the can, it has to pass under the belt to the part of the main body, so it is difficult to install the can unless you loosen the belt. If you loosen the belt you can attach it by belt threading so you can not feel the advantage of Kang. Also, when entering the scissors, the entrance is the thickness of the scissors, so the screws stopping the scissors may not fit firmly.
