Your listing may only contain words that describe the item. Words that do not belong to the item make the listing appear in the wrong searches, which makes it harder for buyers to find what they are looking for. A brand may only be mentioned if the item was made by that brand.
Prohibited to write
Brands that did not make the item
Comparisons with a brand, for example “dupe”, “in the style of” or “similar to”
Words that do not describe the item, for example brands or names of items you sell in other listings
Lists of keywords or hashtags, for example names of other characters or lists of conditions, languages and editions that do not apply to the item
Titles and descriptions that are misleading in other ways, for example about the item's condition or size
Allowed to write
The brand with its full and correct name, if the item was made by the brand
The item's actual characteristics, for example condition, size and colour
Words that apply to your specific item, for example language, condition and edition for a trading card
Also check the brand field before you publish your listing, as it is sometimes filled in automatically.
