A Rolled Greeting

I was trotting past the front door when a sharp flap rattled overhead, dropping a thick glossy mailer onto the welcome mat with a soft thud! It stayed curled up like a tight cardboard cylinder. Curious about what kept it furled, I knelt on the bristly coir fibers and gave the edge a gentle unroll with both gloved hands. Right inside, tucked into the crease, was a small red plastic clip holding the pages neat and flat. Prying open its tiny flexible clamp gave a springy flick that sent a colorful coupon fluttering free across the floor!
