Use shortcuts and templates for descriptions. A template is an already created ad that you just plug in the specific information. Develop a series of them to cover whatever you sell. When filling in the information use numbers rather than spelling out numbers (i.e., use "11" rather than "eleven.") This works for two reasons; A buyer has many ads to go through and the more accurately they can scan (and the faster), the happier they will be with the shopping experience you provide them; and 2) Potential bidders do searches for single items not sets. They key in the item name and search for what they want. Generally, they want something far more specific than a set. And, it is entirely possible to catch potential buyers who were not looking for your item but happened upon it while browsing (often brought there by the numbers match). The idea is to maximize exposure any way you legally and properly can do it.
