Actually, I don't right now. My old one crapped out some time ago and I haven't gotten around to getting another one. Actually, If I could just find the magnets with the right dimensions, I could attach a regular one to the magnet, but we don't have a Hobby Lobby or a Michaels, which is where I would normally look for something like that. I don't think Walmart has them in that size.
Hmmmm. Home Depot and Lowe's have various magnets. Magnetic paper is at Office Depot. And if you do a search in the FReeperville search engine for, "Bumper Sticker," there's some links to good bumper sticker sites on the threads.
