We have a specific thread for authentications here: https://forum.purseblog.com/threads/authenticate-this-coach-see-first-post-for-format.889527/
Read the first post to see what information we need. If the item is listed online, we need a link to the listing and the seller's name. If it isn't online, we need to know where you got it. I'm not seeing any pictures nor a link in your question.
