[EX Q]: Bought this set based on low price and good reviews. Works fine for poking logs occasionally and cleaning up when stove is cold, but while using the shovel in the fire, the black coating started bubbling, then caught fire.
[EX A]: Negative

[EX Q]: This is strictly a tourist rag. Don't waste your time. If your looking for a basic introduction to Voodoo, try Laennec Hurbon's Voodoo: Search for the Spirit; Voodoo & Hoodoo by Jim Haskins; Sallie Anne Glassman's Vodou Visions; Leah Gordon's Book of Vodou or even the Complete Idiots Guide to Voodoo.
[EX A]: Negative
