The most produced corrugated box is the Shipper or Regular Slotted Container (RSC). This box is a tank, and is the ideal choice for protecting your product. Nearly every industry uses the RSC to withstand the punishment of shipping goods in the mail. The shipper is the perfect box for bulky or larger items that wouldn’t fit in a mailer box. Despite a larger stature, the RSC maintains a perfect canvas to showcase your branding.
