Yes! All of our Direct Mail Brochures get wafer sealed before entering the mainstream as per USPS rules. The price for these products already includes wafer sealing. For any other project where wafer sealing may be needed, you would need to contact our Support Team to assist in pricing and placing this order. Please make sure to provide as much information as possible for us to be able to get back to you quickly with a detailed response. Contact Support Team at Support@4over4.com
