Hi mate. I think the issue you will find is people will be reluctant to buy a box, let alone a case, from someone here with zero feedback and no history.
Unfortunately this hobby attracts scammers who would take the money and not send the box, don’t actually have the box and have just used a photo from elsewhere, or have pre-searched the case and found the major hits and then repackaged.
Also if you check the forum rules you will find that because your feedback is less than 10, you would actually need to send the box first and then receive payment once received. If you are prepared to do that it may help your sale.
