All our seconds sale items are damaged in some way, the candles could be damaged in one or all of the following ways;
the candle has damage to the pattern from handling ie chipping of the wax
the candle has sunken, and/or has tunneling
the container has damage or in the case of the tins is discoloured
 
I have done my best to show in the pictures what the damage is, in all other ways the candle should burn as normal.
