Very impressive and cute carrying case
Size: 12.9 inch, Color: Purple Starry Sky, Size: 12.9 inch, Color: Purple Starry Sky
I've been looking for the "perfect" ipad carrying pouch for a while now and this one is the closest I've found. I use my ipad primarily for art so I always have a stylus, a sketchbook and various odds and ends with me. My 13 inch ipad while in it's bumper case fits in the sleeve easily without the stylus attached and in the main compartment with the stylus attached. There is also enough room for an extra sketchbook/kindle/keyboard in the main part of the bag The zipper quality is nice and I like the feel of the zipper pulls. The handle on the top is very convenient. The crossbody strap is the only thing I'd be a little concerned about because the attachment hardware is plastic but it doesn't feel flimsy at all. The padding is a good amount and I think I would feel safe with my ipad in it with a less robust or even no case. Also I'm just really happy that it had some fun and cool colors available, I'm tempted to pick up a more 'business like' color in the future.

Nice sleeve
Size: 13.3-14 inch, Color: Apricot Flower
Bought this for my 14" HP Omnibook 5 and it fits perfectly. I would have preferred double zippers for security and easy of opening, especially the front pocket with its giant flap. Having both grab handles and a shoulder strap is ideal, even though attaching the shoulder strap is difficult. Overall, it's cute (I got the apricot blossom pattern) and functional.

A Great Buy And Very Pretty

I just love this tablet sleeve bag! The boho design is so pretty, and the sleeve bag is very well-made, with inside padding. The zipper is easy to open and close-- love the shoulder strap, too. A quality purchase all around.

Better than I expected and sturdy too
Size: 9-11 inch, Color: Cloudy Blue
I love it so much I bought 2 more and got one for a friend. It’s the perfect size for my iPad. The charger and cord. Pens and paper and a small/ paper back book. The strap is adjustable and can be removed and stored in the inside pocket. Plus the variety of colors and patterns is great as well. Makes a great gift for someone who is hard to buy for.
