Calvin Klein Black Backpack

Classic style! Calvin Klein black backpack. Perfect for everyday use, it combines elegance and functionality. My daughter used this for school for a few months. I cannot tell if it’s leather or pleather. My guess is pleather. I tried google but no luck. Some marks which are shown in last two pics. Want to clear out. All zippers and straps are working fine. Front ring is to hang a key chain (I think). But any two items from my closet and save 20%
