Purchased on Amazon. I tried cutting and applying a small piece, but my family doesn't seem to like the color, so I've decided not to use it. They don't seem to understand that it won't have the same color as regular film because it's a one-way mirror. It's a shame, but I'm selling it at a clearance price.
