Planning a wedding, graduation party, or special event? These A4 brown envelopes from Eupako are exactly what you need to mail your invitations in style. Each envelope measures 4.25 x 6.25 inches, making them perfect for standard 4x6 photos, cards, invitations, announcements, thank you notes, and RSVP cards. The self-sealing flap is genius - no more licking gross glue or struggling with moisture. Just peel off the protective strip and press the flap down for a secure, permanent seal that keeps your contents safe during mailing. Made from heavy-duty 120 GSM kraft paper (that's 32lb bond/80lb text weight for you paper nerds), these envelopes are thick, sturdy, and completely opaque to protect your privacy. The natural brown color gives them that rustic, elegant look that works for any occasion from weddings and graduations to birthdays and baby showers. They're also printer-friendly, so you can run them through your laser or inkjet printer for addressing without worrying about smudging or jamming. With 100 envelopes in the pack, you've got plenty for your mailing list with extras for mistakes or future use. Eupako specializes in paper products, so you know you're getting quality that will make your special mailings look professional and thoughtful. Whether you're a bride planning her big day, a parent organizing a graduation party, or just someone who appreciates quality stationery, these envelopes deliver both style and functionality. They're one of those simple things that can make your special occasion mailings feel so much more polished and put-together. Your guests will be impressed before they even open the invitation!
