How to ID Toasted Cinnamon Oak on a carton

1. Read the brand strip: it should say Harmonics (Costco-era), not TrafficMaster, LifeProof, Pergo, Style Selections, Select Surfaces, or a generic warehouse house brand.
2. Match the color name Toasted Cinnamon Oak exactly. Do not treat Spiced Applewood, Honey Maple, Premium Oak, Newport Oak, Frontier Oak, or Harbor Scraped Oak as the same SKU even when the plank looks warm oak or cinnamon-toned.
3. Look for longer Costco-style item number 1203881 when that string appears on the carton end or in depleted-list copies. Cite it when you photograph the carton.
4. Photograph the full carton end (brand strip, color name, 1203881 when present, sq ft / plank count).
5. Measure a spare plank (thickness with pad, width, length) before you post a Match listing.
6. Confirm locking on a spare plank. Many Harmonics cartons used Uniclic; a different profile will not click in even if the oak visual looks similar.
