Soldering is a special 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 and a weakness against aging. The handmade cables sold here are created by workers who have learned soldering skills and perform appropriate soldering. Please use them with confidence.
