E-bayers have their own way to describe their items, this is mine. Good used will have scratch marks and show some wear. Good lightly used has scratch marks, very light wear. Good very lightly used might have a few scratch marks, very light wear. I'm sorry but FLAT RATE boxes can not be combined.
I have been packing breakables and dishes for years! I use fresh bubble wrap and packing peanuts, and as I pack thousands of dishes each year, I do it very well. However I use the postal service and at times they do not understand the word "FRAGILE", or they have seasonal workers. This is why I insure all boxes. If your order does have any damage, you are required to keep the box, all packing materials and the damaged item for any claim.
May you always know that God loves You!
