I use a combination of two eyelash curlers, both by Tweezerman. I use the corner eyelash curler to do my outer lashes (it's hardest for my outer lashes to hold a curl, so I have to do this), and then the supercurl (I think) to curl the rest. It's a plastic curler, so you can use a blow-dryer to warm it up first, and that helps the curl hold longer. It's the best way I've found to get a long-lasting curl.
