Melt them inside of one of those decorative candles that has other shit like cinamon bark or leaves inside it already. Just cut out a small hole after you peel off the sticker on the bottom, put them inside that wrapped in a baggie, then melt the wax back in place and glue the sticker back. Thats how you mail it anyway, should work just fine in luggage too. Just put it and some girly soap or something in a paper gift bag and stuff some of that tissue paper in it and make it out to some random chick like you're bringing back souveneirs.
