What fits in a 12" x 18" bag?

A 12" x 18" flat bag holds items up to about 11.5" wide and 15" long, leaving room at the top to tie it off or heat-seal it. It is a good fit for flat letter-size (8.5" x 11") paper, folded shirts and sweaters, binders and medium parts. At 1.25 mil (lightweight), it is made for light items that need a little more puncture resistance.
