it wasnt listed correctly please read the rules and use the template.
also posting in a lot of threads one after the other in a short space of time to get to 50 posts and then immediately posting an item for sale when you get to 50 posts looks suspicious.
I am not saying you are going to try rip anyone off but if I saw someone try to get to 50 posts then immediately sell something I would be wary of buying from them.
Resubmit your thread with the correct template and it will be approved.
