Soldering is a specialized process that is difficult for amateurs to judge the quality of. Even if the soldering appears to be done properly at first glance, if appropriate measures are not taken, it can affect the quality, such as a decrease in joint strength or vulnerability to aging. The handmade cables sold here are made by workers who have learned soldering skills and perform appropriate soldering. Please use with confidence.
