Help uploading item to MP!

[Lamilya Toxx]

Hi, I'm new to selling items on the MP.  I have a huge amount of gacha items I want to try selling (for the same amount as or less than what I paid for them).  The permissions are set correctly, they're transferrable and modifiable.  But for some reason, every time I try to send them to the MP, I get an error message that it's an unsellable item and that it's probably a permissions issue.  I've sold them at yardsales in the past with no problem, I'm just trying to avoid paying rent this time.  I would really appreciate any help figuring out what I'm missing (it's probably something totally obvious, lol).  Thank you!

If they are one-of-a-kind items -- that is, items that YOU do not have copy permission on -- then you can't upload them to Marketplace.  The only way to put one-of-a-kind items (like breedables) there is to use a Magic Box, which was the technology that Direct Delivery replaced two years ago.
