Condition the seller picked: New with tags

Listing description

Camel wool blend coat, size M Single breasted with horn buttons and two front pockets. Bought last winter and wore it maybe three or four times to the office. I took the tags off but I think I still have them somewhere. There's a tiny mark on the left cuff that you can only see up close, otherwise it's in perfect condition. Dry cleaned before listing and stored in a garment bag, from a smoke-free home. Length 98 cm, chest 52 cm across laid flat. Happy to send more photos. I post within two days of purchase.

Fields

  • Condition the seller picked
  • Listing description

Context

Condition levels on a second-hand marketplace for clothing, accessories and electronics. The seller picks one level from a list and writes a free-text description. Buyers rely on the level; a description that shows the item is in worse condition than the level allows leads to "not as described" claims. New with tags: never worn or used. Original tags, labels or seal still attached. New without tags: never worn or used. Tags, labels or seal removed or missing, or the box opened. Very good: worn or used a few times. No flaws, or one small flaw that is only visible up close. Works fully. Good: worn or used, with visible signs of wear or a minor flaw that the seller discloses. Works fully. Satisfactory: clearly worn, or several flaws. Still usable, and any fault is minor and does not stop the item doing its main job, such as a stiff zip or a battery that holds less charge than new. Not working or for parts: broken, does not do its main job, or is missing an essential part such as the charger for a device that cannot run without it. Trying an item on once without wearing it out is not use. Washing or dry cleaning is not wear on its own. The listing title may appear at the start of the description.

Questions

  1. Does the description say enough about use and wear to judge the item's condition? Yes / No

    Read the listing description. Does it say anything about how much the item was worn or used, its wear, its flaws or whether it works, enough to place it on one of the condition levels in the context? Yes: The description says something about use, wear, flaws or working order. No: The description only names the item, its size, colour or price, or gives no information about condition at all.

  2. Which condition level does the description support, ignoring the level the seller picked? Choice

    Read only the listing description, not the condition the seller picked. Using the condition levels defined in the context, which level do the facts in the description support? When the description gives facts that fit two levels, choose the worse one.

    • New with tags The description says the item was never worn or used and the tags or seal are still attached.
    • New without tags The description says the item was never worn or used, but the tags or seal are gone or the box was opened.
    • Very good The description says the item was used a few times, with no flaw or one small flaw only visible up close, and it works fully.
    • Good The description admits visible wear or a minor flaw, and the item works fully.
    • Satisfactory The description admits clear wear, several flaws, or a minor fault that does not stop the item doing its main job.
    • Not working or for parts The description says the item is broken, does not do its main job, or is missing an essential part.
  3. Does the description state something the condition the seller picked does not allow? Yes / No

    Read the condition the seller picked and the listing description. Using the condition levels defined in the context, does the description state a fact that the picked level does not allow, such as use on a "New" item, missing tags on "New with tags", a visible flaw on "Very good", or a fault in how the item works on "Very good" or "Good"? Count only facts that make the item worse than the picked level allows. A description that is vague, or that makes the item sound better than the picked level, is not a contradiction. Yes: The description states at least one fact the picked level does not allow. No: Everything the description states fits the picked level, or the description says too little to contradict it.

  4. Does the description say the item has been worn or used? Yes / No

    Read the listing description. Does it say, in any words, that the item has been worn, used, played, run or carried, even a few times? Trying an item on once without wearing it out does not count. Yes: The description says the item has been worn or used. No: The description says the item is unused, or says nothing about use.

  5. What is the main flaw the description discloses? Choice

    Read the listing description. Which kind of flaw is the most serious one it discloses? A fault in how the item works is more serious than damage, and damage is more serious than a mark or wear.

    • No flaw described The description mentions no flaw, wear, fault or missing part.
    • Cosmetic wear General signs of use: pilling, fading, light scuffs, softened fabric, worn soles.
    • Stain or mark A stain, mark, spot or discoloured patch in one place.
    • Physical damage A tear, hole, crack, dent, chip or broken fastening.
    • Missing part A missing accessory, belt, button, charger, cable, box or other part.
    • Functional fault The item does not work fully: a battery, screen, zip, button or mechanism fault.
    • Odour A smell of smoke, damp, perfume or pets.
    • Alteration or repair The item was hemmed, resized, repaired or modified from how it was sold new.
  6. Does the description say the item does not work fully as it should? Yes / No

    Read the listing description. Does it say that any part of the item does not work fully: a battery that does not hold its charge, a dead pixel, a zip that sticks, a button that does not respond, a fault that comes and goes? Yes: The description reports at least one fault in how the item works. No: The description reports no fault in how the item works. Cosmetic wear and marks are not faults.

  7. Does the seller express doubt about whether the item is genuine? Yes / No

    Read the listing description. Does the seller say they are not sure the item is genuine, or word the listing to avoid the question, for example "not sure if real", "no proof of purchase, bought abroad" or "sold as seen, no questions"? Yes: The seller expresses doubt about authenticity or avoids it in words like these. No: The description raises no doubt about whether the item is genuine.
