Remarkably low prices and definitively high-quality office products. At Blue Summit Supplies, we’re disrupting the status quo. We’re doing away with the bloated, outdated practices of the traditional office supply industry to focus instead on simplicity. Our company’s purpose-driven model and lean manufacturing methods have been carefully engineered to directly feed the extraordinary value we’re able to provide you, our customers. Visit the Store Visit the Store Visit the Store Welcome to your new favorite office supply store! It’s no secret that #10 security envelopes are the workhorse of business mailing, and we’ve designed our standard #10 envelope to keep your documents safe and secure behind a strong permanent seal throughout transit. Our most popular business envelope is made from a durable 24lb white wove paper and comes equipped with a low profile flap design. Easily fold and stuff up to 10 sheets of standard letter size paper inside with room for a #8 or #9 return envelope – so you can make it simpler than ever for your clients to quickly return payments to you. And with our dark security tint lining the inside, your confidential mail will stay concealed and secure all the way to its destination. It’s an envelope choice that’s simple enough for everyday letters and statements, yet professional and secure enough for high-profile business communications. Simply pull the backing off the envelope's flap to reveal an adhesive strip that can be folded over and pressed down to seal contents safely inside. Moisten the strip of adhesive found on the envelope's flap and fold over to seal contents securely inside. No moisture is required, just flip up the bottom flap, fold over the top flap and press to secure contents safely inside.
