I've tried three or four different erasers and nothing works. Terrible smudging from minor, lightly drawn lines. I'm sure these are great for some applications, I can't recommend this product for sketching...especially if you make a lot of mistakes like I do. Honestly, this sketch book is headed for a drawer, never to see the light of day again, or straight into the bin. Very disappointed...
This book has withstood the abuse of being used in the field for military operations and accidentally being washed when left in uniform pocket. Great product overall.
Time will tell since calving season just started--appears very durable. It would be nice if there was a sleeve on the book to hold a pen or pencil. Whatever you write on the pages is permanent. Even pencil does not erase but it will be nice to know nothing will smear and be hard to read at the end of the season.
I fell in love with your products while I was in the army stationed at Fort Hood, Tx. I used and I still use to this day the no 980t tactical. The grids provided are great for sketches, because it makes it easier to take a picture to send back to my home office and not some ugly chicken scratch. All the other steps and actions that you have added in the book, aids those to be a better a leader. Even though it is tactical it still carries over to every day life.
