This is an earthing kit I purchased on Amazon. I bought a no-brand product, but it arrived in an HKS case. However, the font of the letters printed on the cables doesn't seem original, so I don't think it's actually HKS. I only used one 80cm cable, so this is the remaining kit for sale. Shipping costs are high if I include the case, so I'll only send the cables, terminals, and screws. Thank you.
