It entirely depends on the level of protection you're looking for, for that specific device.Some prefer the sleek look and feel of a Skin. They protect your device from scuffs and scrapes, and don't add any extra bulk/weight to your device.Some prefer more heavy-duty protection. If that's you, the Skin + Case protection option is 100% the way to go.When you opt for the Skin, you get a premium vinyl decal for your device. If a MacBook Skin, you’re able to select the level of coverage you prefer: top, top + bottom, or top + interior + bottom.If you opt for Skin + Case protection, you’ll get the Skin, plus a Clear Hard Case designed to clip over top of the Skin. Hot tip: Clear Cases can be reused with your next Uniqfind Skin, or on their own.
