Using this Incase laptop sleeve is a breeze. Just slide your 12' MacBook Pro into the sleeve gently. You can use it on its own or put it inside your bigger bag for extra protection. When it comes to maintenance, you can simply wipe it with a soft, dry cloth if it gets dirty. Avoid using harsh chemicals or abrasive materials as they may damage the sleeve. Also, don't overstuff the sleeve or put sharp objects in it to prevent scratches to your laptop.
