Brilliant info and your photos look fine too me. It is a hard job selling on eBay full time and you are completely right eBay does often like to side with the buyer. But your on the right track if as you say you are showing the imperfections on your items. As long as you describe the item and photo it to a reasonable standard, you shouldn't have too many returns. I sell approximately 150-200 items a month and I usually get about 1-2 returns each month, so about 1%, which is not bad at all. Keep up the posts, upvoted and followed :)
