It’s hard to beat this selection of blue window envelopes. We carry different sizes, flap styles, closures, and security tints—all in various shades of blue, from light pastels to richly dark navy shades. No matter what kind of blue window envelopes you’re looking for, whether you need them for the office or at home, we should have exactly what you need. Look through our entire selection.

There’s more than one shade of blue.
You might be able to find a blue window envelope somewhere else, but will they have the full selection of blue shades we carry? From Presidential, which has a touch of purple, to Sea Blue and it’s ocean-like, creamy aqua blue, it’s hard to imagine a more extensive choice of shades in blue window envelopes. Choose the blue color that reflects the message you want to send, even if that message is I like this color.

Multiple flap styles, all in blue.
Flap style is a matter of personal taste. Some people only use square flaps, while others prefer v-flaps. We have blue window envelopes in a variety of flap styles, including open-ended options. Which means you won’t just find envelopes in the perfect blue shade, you’ll find the exact combination of shade and flap style you prefer.

Even more blue window envelope options.
Once you’ve picked your shade and flap style, there are still more options to consider. Do you want to avoid licking or moistening the flaps to close them? Then pick an envelope with a peel-and-stick closure. Do you need to ensure confidentiality? We have security-tinted blue window envelopes designed to hide what’s inside. If you don’t care about that, we also carry non-tinted versions. Whatever you want, your blue window envelopes are here.
