Bought this to replace an existing computer bag that I use for college. I typically hold a lot of stuff and my bags become heavy. This bag holds up! Carries a lot of stuff, including my standard laptop, a few books, etc. It also has a zipper area to put things I need to find easily. Style and design also very cute. Honestly, a great bargain.

love the colors

Color: Blue Flowers

I love the colors on this bag, and the size is big enough for me to put my normal purse stuff in plus pack my lunch in it, and there are 2 drink holders on the ends. It seems made from waterproof material. Although I thought it was canvas when I ordered, and I thought it had a padded computer pocket. That isn't true. But I was looking at so many tote bags, I may have gotten them confused in my head. But it seems really well made and there is plenty of room in the bag if you have a padded computer sleeve for your laptop and then place it in the bag.

It’s a Nice Big Bag!

Color: Blue Flowers

I bought this bag for my mom as a Christmas present and she loves it. She’s a big purse lady, so it is the right size for her. It has all the pockets in the right places and she loves the pretty floral design.

Love the style and Multi pockets!

Being a traveling float Phlebotomist for a very large company I need a bag that is extremely well-made holding my schedules.. my books, my PPE outfit, and all other essentials I need for my position. This bag is definitely the one very well-made, multi pockets more than enough room for everything that I need to carry all my equipment for me… to each job. Definitely would recommend this to anybody who travels in their job. Definitely purchased from this company again. Shipping was very fast and the product is in my eyes perfect.!
