Material options

With a gorgeous matte finish, our classic white custom cardboard boxes are our most popular option. It takes well to any color especially bright, vibrant hues.

Brown inside and out, our natural kraft cardboard is as eye-catching as it is rugged. It works well with deep colors, giving an unmistakable warm and muted finish to your design.

When you're ready to get fancy, Dreamcoat is the obvious choice. It's our premium bright white material with a satin finish. You'll notice a shimmery, satin sheen on printed, high-saturated areas that creates a striking contrast with unprinted areas.
