Seiwa Kogyo, made in Japan, grounding cable, 20SQ thickness, 40cm length (HEC-20-40). It's a beautiful item, with only slight marks on the terminals from installation/removal. The price includes shipping via Nekopos. I think it has a good thickness and length for easy handling, even for canceling the idling stop function. If you are looking for 20SQ x 40cm, please consider this.
