Perfect campus bag!!
Color: Leopard Spots
Used it as a school bag for college since I prefer shoulder bags over backpacks. Sturdy. Holds SO MUCH! Books, binders, School materials, food and snacks, giant water bottles....and CUTE asl!!! Got this in my last year of college. Wish I had found this bag sooner so I could have used it throughout all of my college years!

Beautiful, sturdy and comfortable!
I am very satisfied with this bag! I honestly thought that because the price was so low that it would be more of a lightweight beach bag, however, it is very sturdy and holds so many things. The straps are very thick and comfortable. There are a few pockets inside zippered pockets of some side pockets and a front zipper pocket. I get so many compliments on this bag. Two of my friends actually bought the same bag! I honestly want to buy another one just in case somewhere down the road something ever happens to this one because I am obsessed with it. I use it every day for work is very easy to clean as well. It’s almost like a neoprene type of fabric so it wipes off very easily. I highly recommend this product.
