(This message was brought you by a disgruntled daily user of candles who has a bag of stick candles from Hema in her drawer which turned out to be white on the inside, so she can only use them for secondary purposes, and who now has to travel across the entire city to get candles from a store which sells the ones made entirely from black wax)
