You can sell a vast array of products on eBay. Just keep in mind that eBay does have a list of prohibited items and of course, you can't sell illegal items.
Are there any costs?
eBay charges a small fee to list and sell on their marketplace. For an individual account, each listing costs $0.30. You can create an eBay store starting at $15.95 per month with no initial listing fees. For both types of accounts, eBay will charge approximately 10% of the total price (item price + shipping charges) when you make a sale. However, all sellers get a number of free listings each month for most categories. Learn more about eBay fees here.
How long will my listing stay active?
Listing duration varies by each country. With Nembol, you can select 7 days or "Max possible", which means the longest amount of time that eBay will allow you to keep a listing active in your country.
