Just installed and launched the new app from Neenah called Cabinet. The simplistic navigation and friendly interface lets you peruse through papers by color, weight and even lets you save your favorites.
Despite it's ease of use, you'll still need to use a swatch book to get up close and personal with the paper you're after. Don't have a swatch book? The app gives you the option to order one via a quick redirect to the Neenah site.
