Looking for shoe box mailing boxes or cardboard postal boxes for bulky fashion items? The S343+ Mailbox pop-up mailing box is used by the largest fashion retailers both as a shoe box mailing box and as a clothing shipping box for multiple orders. Thanks to its unique security features, such as the the side locks and tamper-evident tear-strip, you can safely and securely mail high value designer items. It is very strong and three times faster to pack than a standard '0201' style corrugated box. Using our strong and stiff corrugated cardboard with an attractive 'kraft' finish inside and out, the S343+ is one of our most popular mailboxes and is being used for a wider variety of contents. All mailboxes feature our leading hot melt peel'n'seal / red-tear-strip system for easy sealing and easy opening of the mailbox.  Our entire mailbox range is also 100% recyclable and FSC® certified.
