Our custom window envelopes come with one or two windows. The one window envelopes can include your logo and business information, while the two window envelopes are usually plain. They can occasionally include one line of text between the windows.
Window envelopes are perfect to save time addressing envelopes. Use with pre-printed forms and simply insert and mail out to customers and prospects. They are most commonly used for checks and invoices. More precisely, one window envelopes are mainly used for pre-printed forms like statements, while the two window envelopes are mostly used for checks or computer forms which allow the recipient's name to be generated by the software.
