Very big! It fits my textbook and laptop, book, switch, wallet etc. It doesnt have a zipper, but big enough for if youre trying to bring all of your stuff with you for the day. The strapnis adjustable as well. Its a beautiful color, great quality, and 3 inside pockets with a zipper on one. A great bag for traveling.

So tiny, so elegant

Color: Gold Harlow, Size: 16MM, Color: Gold Harlow, Size: 16MM

This ring is so elegant and beautiful. It is tiny, so if you don't have the best eyesight, this will not work for you. The band fits snugly on my size 7 ring finger. I love the shape of this ring so much. It seems like really good quality and has kept time accurately so far. Definitely worth the money, in my opinion
