The Karbon Protective case is very light weight and thin, thinner than the Sandstone case. I love how thin it is and how it doesn't add any bulk to the phone. It has a soft and smooth surface. There's some grip to it, not as grippy as the Sandstone one but that's expected. Love the silver 1+ logo but if you look closely, there are some stain on the logo. Delivery took a little over 1 month. The price here also cheaper than the other sellers.
Original case. Recommended !
