Are SUPERBOX black boxes dyed?
No, our black boxes are not dyed. They are made from decorative black corrugated cardboard, so the entire cardboard layer, including the inner fluting, as well as the edges, are naturally black. This gives the boxes a uniform, luxurious, and sturdy appearance without any added color.
Edges of dyed cardboard are usually white, so dyed boxes look visually different from our black corrugated cardboard boxes. Additionally, naturally black corrugated cardboard is more durable and resistant to everyday use, as dyed surfaces can start to crack along the fold lines.
