Close-up product photograph of a blue and white 20 kg bag of UZIN UTZ NC 550 levelling compound. The front of the bag shows a large 'NC 550' label in bold letters and the UZIN logo at the top. A vertical list of multilingual product names runs down the left side, and to the right there is an 'ECO2 CHOICE' footprint icon, a QR code and several certification marks including EC1 Plus and the Blue Angel. The weight '20 kg' and article number 'Art. No. 176915' are visible near the bottom. The image is taken with even studio lighting and a slight perspective that reveals the front and part of the right side of the packaging, suitable for e-commerce, product catalog or technical documentation.
