Feel like humming tra la la la? Sure you would! Made from wooden pulp and bleached as per requirement, these mailers take packing stylishness a notch above the rest. We make these classy looking self-sealing mailer envelopes with side gussets to add more space, strength and flexibility. These mailers are made up of a thin board that’s adaptable enough to accommodate various products. They are ideal for shipping soft goods or unbreakable items. Not to mention the peel-and-seal flap; the food industry particularly dotes on these for their designs and durability. You could also pick its thinner version minus the gusset.
