Query: These are a joke!

These so called "incense " are sold on Amazon as ear candles! It even says "ear canceling instructions included" (which btw is not true...). Please safe your money, because they do NOT work! The yellow, brown residue is NOT your ear wax, but residue from the candle We even burned one by itself, and we used 2 in our ears... Result was the same: brown, yellow residue. Even the one which we just burned by itself I can not belief that Amazon endorses these as ear candles... ! . I sent mine back for a full refund!
