The human-readable label for the item condition. Display names are localized for the site on which they're listed (not necessarily the site on which they're viewed).
In item results, this is only returned when the seller specified the item's condition using a structured format eBay recognizes.
When conditionId is also present: Most categories use the same display name for the same condition ID. Some categories may override the display name based on buyer expectations for items in the category. For example, condition ID 1000 could be called "New" in one category and "New with tags" in another. If an item is listed in two categories, the primary category controls the display name.
Behind the scenes, eBay's search engine uses the ID (not the display name) to determine whether items are new, used, or refurbished. So, if you need to normalize the conditions across categories (such as to group items by condition), it may be easier to use the ID and then show the varying display names for reference.
In condition histograms: If you search against a specific category and some items match based on their secondary category, the histogram only shows the display name if the secondary category supports the condition. (Condition IDs and names are dependent on the primary category.) However, the histogram shows the condition ID and item counts. This should only occur in a very small percent of results. As a workaround, you can fill in the missing name based on the "Item Condition IDs and Names" (link below) or based on the condition from an applicable item in the results.
For example, suppose a seller lists a concert T-shirt in a clothing category with the condition "New without tags" (1500), and also in a music accessories secondary category (where "New without tags" isn't a recognized condition). If you specify the music accessories category in your request, the condition ID (1500) is shown in the histogram, but not the display name. However, the display name is shown within the items.
