Business and Commercial Envelopes

Your business should be as professional as possible. Business and commercial envelopes are the right choice for both your clients and employees. For more serious circumstances, choose a crisp white or off-white envelope. If you really want to stand out, choose an envelope in a popping hue, like red or yellow, or an envelope that matches your clients’ company colors.

Social and Invitation Envelopes

Social and invitation envelopes are great to use for events, greeting cards, thank you notes, photo cards, special announcements, weddings and more. If you want your message noticed, pick an interesting size, material style, and color! [table id=5 /]

Promotional

Promotional envelopes are your go-to for any other need that isn’t social or business related. For example, if you need to send something that needs some protection, choose our bubble mailers. Or maybe you need to send artwork or important papers. Choose our sturdy photo mailers! OR maybe your company wants to send out larger magazines or promotional brochures. Our large open end envelopes are the way to go. Basically, anything that won’t fit into our other envelope categories, you can find it in the promotional group of envelopes. [table id=8 /]

Flap Styles

In addition to sizes, there are flap styles to choose from! Check out the picture below to see what your options are!
