The sleeve is smooth on the inside and I feel confident that it won’t scratch or leave any abraisions on the laptop.
This is a great buy, especially for the price. I purchased the 13 inch for my new 2018 MacBook air, and it fits perfectly!
I absolutely loved the interior which was super soft and wouldn't scratch my new laptop. The outside was a nice material too.
This case is durable and super nice. I feel pretty good about the protection it gives my laptop and it still fits in my backpack.
