Looking for Mamu Jersey

Hey guys was hoping you could help me out. My girl wanted a Mamu jersey and thinks she bought one off a scam website. I know off the top that there is the NBA store, Real sports and Sportchek. However of those 3, none have any Mamu jerseys and the customs have a 12 character limit for the name on the back. Are there any options we're missing here to get an official jersey? Do they perhaps get restocked at certain times? Any help is greatly appreciated. Cheers.
