I've lit several sky lanterns before, they're the coolest thing ever. But these are different, very different from what they used to sell. The old ones were made of strong paper, already-attached fuel supply that lights quickly, and is very safe. These are made of paper that have tears for every other balloon, have a wax square for the fuel supply (you have to attach yourself, with chance of breaking/crumbling) that takes 30 min to light, and once it does light, it flies horizontal rather than UP. I'm not only writing this review cause I'm ticked off, but because I don't want YOU to buy these for a party or occassion and be sad when you realize they don't work. Waste of money, dangerous, crappy. Don't, please don't, buy. Trust me.
Respectfully,
Jeremy
