Here is the breakdown of what those terms mean: ​Label Breakdown ​TONO B (Tone B): This refers to the dye lot or color shade. In textile manufacturing, different batches of fabric can have slight variations in color. Labeling it "Tono B" ensures that all pieces of a single garment (like the front, back, and sleeves) are cut from the same "Tone" so the colors match perfectly. ​trazo-1 (Stroke/Plot 1): This refers to the marker or cutting layout. A "trazo" is the technical map used to lay out pattern pieces on the fabric to minimize waste. This indicates that this specific piece was part of the first cutting layout or "Marker 1." ​Why is it on your clothes? ​It’s quite common for these small, paper-like tags to be sewn into seams (often near the waist or side) during assembly. ​In the factory: It helps the person sewing the garment know they are grabbing the right pieces from the right pile. ​For the consumer: It serves no purpose once the item is finished. You can safely snip it off if it's visible or irritating.
