Card Listing Writer

# Card Listing Writer

An agent kit that writes sales listings for sports cards and trading cards. You give it your notes on each card. It gives back:
- an eBay title of 80 characters or fewer, with the count shown;
- the item specifics;
- an honest condition description;
- a short description, a photo checklist and a shipping line;
- a list of anything you should confirm before posting.

It also writes the shorter formats used on Whatnot, TCGplayer and in Facebook groups.

It writes. You check and post. It never sets prices or claims a raw card will grade well.

Made by AgentLoomX (https://agentloomx.com). Version 1.0.0.

## Who it's for

- eBay and Whatnot sellers who list cards every week.
- Collectors selling part of their collection who want listings that read well and don't lead to returns.
- Pokémon and TCG sellers who need clear condition grades.
