Two large gray plastic buckets with blue lids placed side by side and slightly overlapping against a white background. Each bucket has a bright yellow rectangular label printed with the brand 'codex' and the product name 'AX 40' and the German word 'FLÜSSIGABDICHTUNG'. The left bucket's label also shows 'GRAU' and an 18 kg weight marking near a barcode; the right bucket's label shows 'GRÜN'. Metal carrying handles are visible at the sides. The photo is a clean, high-resolution studio product shot that highlights the textured rim of the lid, the smooth plastic body and the printed product information; the product is a ready-to-use liquid waterproofing sealant intended for use under ceramic coverings.
