I ordered two tubes of Harris Blockade brazing rod, ordered on March 31, and it just arrived on April 15,2020, it was just a bunch of rod wrapped in tape, now how do I even know what it is. Harris packages this stuff in tubes, I've never seen it bulk. A tube contains 20 rods, I was sent 52 so the math doesnt jive either, it must be you are expected to send it out for molecular analysis and metallurgy workup before using it!
