Or you can get the these, 10 for $10.

I also carry one of these in my workbag.

And then there the Colgate Wisps.

The flosscards are nice in that you get 12 yards in a continuous length. The 'toob' brush carries its own toothpaste, you fill it with whatever brand you want. The Wisps seem convenient at first but the dual packaging makes it hard to use one without ending up contaminating the other.
