Rigid, non-bendable envelopes. Gusseted sides expand to a one-inch depth to allow for odd-shaped or thicker items. Solid fiber exterior replaces the need to use a pad to stiffen the package. This feature helps reduce packaging and shipping costs. Stay Flat mailers will not bend or be crushed. Self-seal strips secure your package. Case count: 100.
