I ordered a whole set (three wick 6", 1 wick 9", 6", and 3") in varying colors for the holidays to replace a set I had used for several years.
Reply: Most likely the cracks/seems that are forming down the sides are because a some point some liquid wax was allowed to run over the edge. They are not like that when they leave our factory. They should still burn fine just keep an eye on them and make sure you have them on a plate in case they start to leak.
