all good questions. I will ship in a flat rate box, filled with padding... im gona try it with my own nail polishes and make sure that they dont break before i send it out with the winner's polishes. They are new as in never used on nails before.. they were opened 1x to make a swatch on a paper so I knew what color I had. I will use a tracker so I know you receive it and if it goes missing I will refund since I don't own multiples. Hope I answered all your questions.
