#11 Envelopes - 4.5 x 10.375

  • #11 Envelopes - 4.5 x 10.375
    • More on #11 Envelopes
    • #11 Envelopes are categorized as business envelopes. Slightly larger than the most common #10 envelope, you'll be able to fit more folded pages inside all the while keeping that professional style. Sometimes used as an outer envelope to fit a #10 return-envelope inside, this 4.5 x 10.375 envelope is very versatile. Use them for invoices, checks, even advertisements. Yet, just because these are categorized as business envelopes doesn't mean you can't use them for personal purposes as well! Since these envelopes hold a standard piece of paper folded in thirds, use them to write those special letters.

      We want you to easily choose one that fits your business needs, so we have grouped our 4 1/2 x 10 3/8 envelopes by color. Choose a color that matches your company logo or go for a complementary color. Our choices come in either regular or policy open end. And most of our colors have different shades to choose from too! So whether you want a darker, more professional shade or a brighter, louder shade, we have it all. We even carry clear envelopes for a unique alternative to the manila envelope most businesses use. But don't worry, we carry those too. So shop #11 for the perfect business accessory.
