With customizable designs, sturdy materials, and a professional finish, our mailer shipping boxes ensure your brand speaks volumes—before the box is even opened.


    What Are Sleeved Mailer Boxes?

    Sleeved Mailer Boxes are a two-piece packaging design that features a tray-style mailer box enclosed within a custom-designed sleeve. This style not only adds a layer of protection but also gives your packaging a unique and professional appearance.

    The outer sleeve acts as both a branding tool and an extra layer of security, while the inner box holds your product firmly in place. It’s an excellent choice for businesses that want their packaging to reflect premium quality while offering dependable shipping support.
