    Product Overview

    Thy Custom Boxes's Mailing Envelopes are the perfect way to send your important letters, documents, or small packages. These envelopes are made from strong paper, so you don't have to worry about them tearing easily. They come in different sizes to fit whatever you need to mail. We offer standard sizes like the common #10 envelope, which is great for business letters. We also have larger sizes that are good for sending bigger items like reports or booklets. Plus, you can choose between envelopes with or without windows. Window envelopes let the address show through, saving you time from having to write it twice. Our envelopes are easy to seal. Most of them have a simple flap that you wet and stick. Some even have a peel and seal strip, making it even faster to close them securely. This means your items will stay safe and private during their journey to their destination. Thy Custom Boxes understands the importance of reliable and affordable mailing supplies. That's why we make sure our Mailing Envelopes are both high quality and budget friendly. Whether you're sending out birthday cards, invoices, or promotional materials, our envelopes will help you get the job done right. They are a great choice for home, school, or business use. You can trust Thy Custom Boxes to provide you with the envelopes you need to keep your mail secure and professional looking.

    Learn More About Mailing Envelopes

    Thy Custom Boxes makes Mailing Envelopes for all your sending needs. Whether you are sending a birthday card, important documents, or even small gifts, our envelopes are built to keep your items safe and secure during their journey. We know how important it is for your mail to arrive in good condition, so we focus on making envelopes that are strong and reliable.

    Sizes and Types

    We offer our Mailing Envelopes in many different sizes. The most common size is the standard letter envelope, perfect for folding a piece of paper in thirds. We also have larger sizes that can hold magazines, catalogs, or even small boxes. Think about what you are sending and choose the size that fits best. You don't want your item to be too cramped or to have too much empty space in the envelope.

    Besides different sizes, our envelopes come in different types too. We have regular envelopes with a simple flap that you moisten to seal. These are great for everyday use. We also have self stick envelopes. These have a sticky strip that you peel off and press to seal. Self stick envelopes are quick and easy to use, especially if you are sending a lot of mail. And finally, we offer clasp envelopes. These have a metal clasp that you can open and close. Clasp envelopes are good for sending items that you might need to access later.

    Strong and Durable Paper

    The paper we use for our Mailing Envelopes is carefully selected to be strong and durable. We don't want your envelopes to tear or rip during mailing. The paper is thick enough to protect the contents from bending and wrinkling. We also make sure the paper is easy to write on. You can use a pen, pencil, or marker to address the envelope without worrying about the ink smearing.

    Secure Sealing

    A good seal is very important for an envelope. It keeps your items from falling out during transit and prevents people from seeing what's inside. Our regular envelopes have a reliable gummed flap that creates a strong seal when moistened. Our self stick envelopes use a high quality adhesive that sticks tightly to the envelope. And our clasp envelopes offer a reusable and secure closure. We test our envelopes regularly to ensure that they meet our high standards for sealing.

    Colors and Styles

    While white envelopes are the most common, we also offer Mailing Envelopes in a variety of colors. You can choose colored envelopes to make your mail stand out or to match your brand. We have bright colors like red, blue, and green, as well as more subtle colors like cream and gray. We also offer window envelopes. These envelopes have a clear window that allows the address on your letter to show through. Window envelopes save you time because you don't have to write the address on the outside of the envelope.

    Uses for Mailing Envelopes

    Mailing Envelopes are useful for many different things. Businesses use them to send invoices, statements, and marketing materials. Individuals use them to send letters, cards, and invitations. You can even use them to organize your documents and receipts at home. Think of Mailing Envelopes as a versatile tool for communication and organization.

    Easy to Store

    Our Mailing Envelopes are designed to be easy to store. They come packaged in boxes or bundles that you can easily stack on a shelf or in a drawer. The packaging protects the envelopes from dust and damage. This way, you can keep a supply of envelopes on hand without taking up too much space.

    Affordable Price

    Thy Custom Boxes believes that everyone should have access to high quality Mailing Envelopes at an affordable price. We work hard to keep our prices competitive without sacrificing quality. We offer discounts for bulk orders, so you can save even more money when you buy in larger quantities. Check our website or visit your local store to see our current prices and promotions.

    Environmentally Friendly Options

    We care about the environment, so we offer Mailing Envelopes made from recycled paper. These envelopes are just as strong and durable as our regular envelopes, but they are made from materials that have been used before. Choosing recycled envelopes is a simple way to reduce your environmental impact. Look for the recycled symbol on our packaging to identify our environmentally friendly options.
