Decided to upgrade my power wire to 0g as well do the big 3 The fuse terminal I purchased looked like this inside, i thought must be bad so tossed it and ordered a new one (different company) and it also arrived looking the same inside. I then unpack my Knukonceptz Ultimate battery terminal and it looks the same in the wire terminals.

Is this normal or safe to use ? Or do I just have some crazy bad luck rn ? All 3 different companies btw.
