Designed specifically for two-up style W-2 forms, Adams® W-2 Envelopes provide a precise fit, so that you can professionally satisfy your tax-season obligations. Interior security pattern and blue tinting help to ensure that all confidential information remains obscured during transit. Left-aligned double-windows allow only the employer’s and employee’s addresses on the form to clearly show through. Each envelope is constructed of woven-finish business-weight paper and features a cost-effective gummed closure, making them ideal for bulk mailings. To help your employees properly identify the nature of your correspondence, “Important Tax Return Document Enclosed” is also pre-printed on each envelope’s face.
