This smart, inside-out design that we developed provides a unique natural feel. Every K3® cardboard wrap has a rough and a smooth side, although the latter is usually on the outside. Aiming to deliver a closer-to-nature hand feel, we simply inverted the yogurt cups’ wraps – which, incidentally, are also used by other customers of ours. As a result, the cups have an even more natural overall look, their eco-friendly properties are underscored by the way they feel in the hand, and the whole package catches the eye right there on the store shelf.
