Made from strong, rigid corrugated cardboard, our self seal mailing boxes provide outstanding protection when sending your items, as well as being extremely secure thanks to the high tack self seal closure strip. Printed 'Handle with Care' these shipping boxes also alert handlers to treat your package kindly!
