Using this Incase laptop sleeve is a breeze. Just slide your 13-inch MacBook Pro Retina into the sleeve. You can use it as a standalone case when you're on the go or put it inside a bigger bag for extra protection. When it comes to cleaning, use a soft, damp cloth to gently wipe the surface. Avoid using harsh chemicals as they might damage the eco-dyed poly material. Store it in a dry place when not in use to keep it in good condition.
