I only had this chain for two to three days, the chain twisted into a knot as I began to pick it up from the counter and o'course because it is so thin - there was no way to undue the tiny knot.  I was unable to retrieve the precious pendant I had on it , therefore I had to just return the chain .  There was no other way.  What a waist of money.  As the saying goes, "you get what you pay for"  everytime.  Those 1mm chains are simply useless, I do not know why that are made.
