At its heart, your item description is an ad. Without making it too obvious, you should be writing sales copy. You're trying to get buyers excited about your products, and that's usually hard - but on eBay, if you have the right thing to sell and give enough details, the buyers almost excite themselves.
Technical Details.
Include every technical detail you know, including the item's manufacturer, its condition, how big it is, where and when it was made, its history, and anything else special about it. Don't be too boring, though: the best descriptions are written in friendly, conversational language, and show a real knowledge of the item. Whatever you do, make sure you tell the truth!
