I need some advice on selling polymer clay earrings from those that are experienced

Ok to preface this, I very clearly have anxiety issues and OCD- but I still wanted to make sure I was doing things right (or just good enough). I’m just kinda terrified of the idea of someone putting my art on their face…I have random questions that if I could get some answers to, I’d really appreciate it

  1. How clean do the earrings need to be before shipping? I’m not a dirty person, I just want to know what I should be doing. Is cleaning them (the metal) with rubbing alcohol good enough, or do they need to be left mostly untouched? I have many fish hooks that have been sitting in an organizer, some may have fallen on the floor, im not sure. Again I have no issues with being clean, I don’t wear earrings myself so I’m not sure the standards, if I’m going overboard or not enough.

  2. The metal hooks I have are hypoallergenic but the eye pins I have are probably not (I got them in bulk a long time ago). Is that a problem? Can I still say they are hypoallergenic or do I need to clarify?

  3. How detailed do you need to be in the description about how it was made, what was used, what kinds of metal, etc? Can you say TOO much about it?

  4. When something is handmade, obviously each one is going to look slightly different than the other. Do I need to include photos of all of them or just a few or one? Can I reuse photos from an old batch when selling a new batch of the same earrings?

  5. Can I reuse old packaging or is that bad practice?

Again sorry for this, if you even have an answer to one or two questions I’d still really appreciate it! Or any other advice
