Very good workmanship inside sowei also outside. Zipper worked very well. In this case also inside again as the outside. To store a lot of possibilities trifles as additional pockets available. Also inside a zippered compartment. Holders for pens and other well-made, but also the clamping device for the block is great. This was also a reason why I bought this because otherwise most only have the option of inserting and that's not so great. Furthermore, you can clipboard (plastic - good processing) also take out if you just need time to write something. Very flexible so also from this perspective.
