Founded in 1920, the Spanish luxury stationery brand El Casco originally gained fame for producing revolvers. The company's firearms were not only highly regarded, but its craftsmanship was also unparalleled. In 1932, El Casco produced its first M-5 model stapler, seamlessly integrating precision mechanical technology into stationery design, which quickly garnered widespread acclaim in the market. Following this success, the brand continued to introduce various desktop stationery products, gradually expanding its scale and reputation.

El Casco's popularity can be attributed to several factors. Besides its industrial design, which appeals to mechanical enthusiasts, the brand's distinctive use of 23K gold as a material elevates its status. Over nearly a century, El Casco has launched numerous iconic products, including staplers, pencil sharpeners, scissors, pen holders, and paperweights. Many of these items trace back to product lines developed in the 1930s, and their classic, retro designs have aged gracefully, earning the admiration of global leaders and elites alike. All El Casco products are manufactured in northern Spain, where each piece of metal undergoes at least six rounds of manual polishing and three different electroplating processes before assembly. This rigorous approach ensures the achievement of a flawless quality and luxurious finish that sets El Casco apart from the competition.

Among its signature products, the M-5 stapler stands out with its unique design and precision structure, enhanced by the luxurious combination of 23K gold and black brass, exuding exceptional style. On the other hand, the pencil sharpener is a timeless classic from El Casco. Adorned with radiant 23K gold, its intricate floral engravings and warm wooden grip showcase the brand's commitment to exquisite craftsmanship, embodying a sense of grandeur. The round viewing window on the sharpener allows users to enjoy the rhythmic process of sharpening pencils, adding a layer of engagement to the experience. El Casco's stationery elevates everyday life, transforming ordinary tasks into moments of elegance and sophistication.
