100pcs 300mm x 400mm Bubble Padded Mailer Envelope

For a polished and professional look, use bubble padded mailer envelopes. These provide a protective seal around the contents, guarding against damage during shipment by absorbing shocks. Self-sealing with a convenient peel-and-stick lip, they provide tamper evidence upon arrival. Constructed from attractive white, fully laminated Kraft paper, these envelopes are lightweight, saving you money on postage expenses.
