The sale photo shows the candles to be one thickness candle, but the actual item I got were tapered candles where the top gets pretty thin. I stocked the candles because of recent NJ hurricane scare, and candles I got from local super market were 12" tapered and about $2 each. These are about $1 each but I would say about the half the size, therefore, no value.
Candles are heavy, so the delivery fee is built into the item. I would say that looking for sale from Target or Costco may get you a better value.
They look like standard quality wax, and although I haven't burned one yet, I assume they will give acceptable flame.
