A Great Buy And Very Pretty
Size: 9-11 inch, Color: Blue Bohemia
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.

It came boxed nicely, Looks just like the picture, easy to use. I have no issues and love it. I even bought one for my husband recently because its easy to use, works good, charges fast and has a long lasting battery. I love that it comes with extra tips and the tips are good quality as well. This is def. Worth the money in my opinion.

Great pen and great price!
Color: White
I’ve been using this pen ever since I purchased my new iPad. Let me tell you that it works great. I use my iPad mainly for writing notes at work and I use it every single day. The pen has help up well. It comes with 4 replacement tips, but so far I haven’t had to replace the tip even though I use it extensively to write. Battery life is pretty good and it charges fast. To me, there is absolutely no reason to spend money on ahig end pen when this one doe essentially the same thing!
