Kraft Brown — The Industry Standard
Brown kraft mailing boxes are the most popular choice for e-commerce businesses, online retailers, and anyone shipping products regularly. The natural brown finish looks professional out of the box, takes branding stickers and labels cleanly, and costs less than white — making it the default choice for high-volume shippers who want reliable packaging without the premium.
