I was nervous about the sizing when I ordered, but this sleeve DOES fit the Fire HD 8 Kids Edition Tablet (7th generation - 2017 release) WITH the case on. There's a little wiggle room left so it's not a tight fit that's difficult to manage, but also doesn't allow for too much room for the tablet to move around. The pockets are good for holding the charger and earbuds. Larger headphones will of course not fit.
The sleeve and handle are well sown with strong stitching so there's no concern (as far as I can see) with the seams coming apart. The material is soft and seems like it will be easy enough to clean. We haven't had it long enough to test that theory though. My only compliant is the lack of color choices. I wish there were more options. I was disappointed to have the buy that exact same color for both of my daughters. There's no way to tell them apart from the outside. Otherwise we're very happy with the purchase.
