The THE ONE Case is part of the DO NOT CROSS world, a collection created to reinvent traditional stationery through Urban Sport aesthetics, contemporary fashion and bold visual identity. Because accessories should be as expressive as they are functional. More than a simple pencil case, THE ONE Case has been designed to accompany everyday life at school, university, work or on the go, combining premium design with practical durability. Made from resistant Nylon & TPU, it is lightweight, waterproof and designed to protect pens and everyday essentials while maintaining a slim, comfortable profile thanks to its extra-flat zipper. Its minimalist silhouette and carefully selected materials make it both functional and visually distinctive. Defined by the collection’s unmistakable DO NOT CROSS statement band, it brings attitude and personality to an everyday essential, transforming a practical object into a design-led accessory with strong visual appeal. Entirely designed and manufactured in Spain using carefully selected resistant materials, it is created to last over time, because at CARCHIVO®, we believe durability is also a more responsible way of consuming. Available in Black and Mint, perfectly aligned with the bold and contemporary identity of the DO NOT CROSS collection.
