Question about mouse being legit

Hello, I ordered my Z mouse the other day and had some concerns after hearing and reading some things. So my friend told me it should come with a case for the mouse and if it doesn’t then it’s not a legit swiftpoint. Is this true?? I didn’t think too much of it but then noticed all the YouTube vids that I watched do an unboxing and theirs came with a case. I only worry because I saw a guy leave an Amazon  review and said his didnt come with a case and inside some cheap plastic bag.  I ordered mine off Amazon for $179 that ships from Petable LLC. Is there anyone who could verify that I’m getting a real swiftpoint mouse? Thank you
