Cute, functional, and well-made
I've had this for a while, and would actually like a larger one too for my laptop. This is very well made, with durable fabric, strong zippers and great padding. I can easily fit my Galaxy Tab S9 in its protective case in the padded section inside, my old Kindle Oasis with cover in the zipper sleeve outside, my Galaxy S23 Ultra, also in its case in the slim magnetic pocket outside. It also holds my charging cords, adapter and earbuds in the case. It fits a lot and is not bulky and easily slips into a tote. I'm glad I picked this up, and when it's not moving around, it's useful just for storing cords and accessories.

Looks sturdy and well-made - waiting to use
Not using this yet, but from examining it, this laptop sleeve appears sturdy and durable. The padded protection looks solid for keeping a MacBook safe.
The design is versatile - works as a carrying case or travel bag. The handle is convenient, and it's lightweight despite the protective padding.
Based on build quality and appearance, this looks like a reliable laptop sleeve. Highly recommend for MacBook owners!

Fits 11” iPad Air with keyboard case
Was looking for something that could hold not just my 11” iPad Air, but also hold it while in its keyboard case with flash sticks and storage for plugs and such. This fits everything perfectly, has good padding, storage pockets inside and out, and feels like a quality build.

Fits in purse without a lot of bulk
I ordered this to use as a travel cross-stitch case on the recommendation of someone else. Surprise, surprise - It doesn’t work as a travel cross-stitch case! (I either shouldn’t have listened or I got the wrong kind).
However, I do have a iPad and it ended up working great for that so I didn’t return it. Padding is good; everything fits; easy to use with a nice handle; the zipper is smooth; color is neutral; doesn’t add a lot of bulk so it’s easy to fit in my bag; provides extra protection although I don’t really need that; seams and stitching are holding up well to everyday use and it wipes clean.
While it doesn’t work for my sewing while traveling, it does work everyday for “work”. So, don’t get this for sewing, but for your iPad (the actual intended purpose!!); for that purpose it works well. My mistake ended up being a plus and the price was good.
