The bag is well made. There is a thick cushion layer, which protects the tablet. The zippers are at the top, so you reinsteckt the tablet on the narrow side. The zippers are well covered but inside and scratch anything.
There is a pen holder, which is very advantageous. While the tablet has its own loop of the pin, which is then at the bottom of the bag. The tablet would then press on the pen. If you were to poke the tablet against the other way around, the cable would be bent and then be broken sooner or later due to cable breakage.
In addition to the pen holder there is also a refill holder in which up to 3 mines can be accommodated.
The bag is used by me daily and so far I could not detect any defects.
