I purchased this item from Excel one year ago. I've only used it a few times since I bought it, so it's in beautiful condition. There are no cracks or sun damage. There is a serial number, but it's in a difficult-to-see location, and I don't want to unfold it, so I haven't been able to confirm it completely. Please check the photos. I have set up a safe authentication service, so please rest assured. Returns are not accepted for any reason after the authentication is complete, to prevent item substitution. Thank you for your understanding that I have set up the safe authentication service to prevent any trouble.
