Where can i buy Magnetic Stripes to put on ID cards?

I am wanting to make ID cards for my employees so they can clock in and out easily. But the problem i have with the erfly pouches with the magnetic stripe is that they are the exact size as the finished size. I want a little extra so i can trim it out and look good. So i wanted just a roll of magnetic stripes that can be encoded. (Preferrably HiCo) I found one supplier but they only deal with huge orders. Does anyone know of a place that sells these?
