When I first bought a Moleskine notebook I was more than a little hesitant due to the price, which was at least twice as much as I would normally spend on a notebook. However, as soon as I started using it I fell well and truly in love and have been recommending them to friends ever since.
These notebooks are made from quality materials and the paper is a joy to write on. I always write with liquid ink pens, including dipped nib pens on occasion and, even though the paper is fairly thin, I have never had the ink seep through. The hardcover opens fully and stays open easily without cracking or bending, allowing for easy writing without obstuction and without damaging the book. The pocket of my notebook is always in constant use, I'm not sure how I ever survived without it. The lines in the ruled notebooks are the perfect size for my writing, small but not too tiny, and they go all the way from one side of the paper to the other without annoying margins to try and control where you write.
I now have a growing collection of various Moleskine notebooks but my original is still in frequent use and, despite being carried around in my bag almost daily for just over a year, it still looks in almost as perfect condition as the day I bought it, with only the tiniest bit of cracking at the top of the spine that has appeared in the last month or so. The rest of my (scarily large) collection of beautiful notebooks is now a backup to my trusty Moleskines. I will be using these books for many many years to come.
I have to admit that the price still makes me wince a little, but now I look at it as an investment and a treat to myself. Some people buy DVDs, I buy notebooks, it's all a matter of perspective, and in my view this is worth the money by far.
