Next time buy a swisher. Those things are so thin that .5 grams if broken down right can fit in one (expect it to be skinny) but a dime can make it fat. I hate big cheap cigar's like Phillies and shit like that, buy a cigarillo like Swisher Sweets. As far as keeping it sealed, you dont need to light it with a lighter or pop it in the microwave. The only thing you need to do with a Swisher is lick it with your tounge, those things are sticky to the point where when you put it on your lips and try to take it off you feel it stick a little bit to your lips, those things are perfect and roll easy but the taste can cause nausea over time and they are very mild.
