Friends. Foam. Fun. For any coffee lover, these are three of the most important things in life. Celebrate the beverage that helps fuel us on National Coffee Day (September 29th) with this thoughtful card. Showing three friends enjoying some cups and some laughs together, it's a great way to let your own ”partner in caffeine” know that you're thinking of them and can't wait to sit down with them again for your favorite drink to share together.
