First I must say that I always thought other books are just as good, with Moleskine I would only pay the price. But then I read in reviews that it is really recommendable. Since the price was then reduced, and it took me a sketchbook for drawings with ink pens or wing tips, I have carried away, and I must say I am pleasantly surprised! When opening I thought the first hand, this is only the front sheet and so so thick, but each side is so thick! Nevertheless Print Fineliner / ink easily. But it's not so much that you can look at the drawing on the back again here;) This is also a star deduction! Otherwise typical Moleskine design, which I particularly like. Simple, but nice. The Folding rear is also handy because I pack from magazines torn pictures etc. as in inspiration. For life or capacity I can not say anything yet. I'm here but good things (when I look at the processing). Overall: For the price, one could require completely impermeable sides. Still, I'm happy and do not regret buying, especially because I have not found, the better the price-performance ratio.
