When it comes to everyday carry, a small pocket notebook is usually fine. But if you're a professional who needs a lot of page space for your notes, ideas, blueprints, or whatever else, a full-sized portfolio can be an absolute necessity. And few, if any are quite as beautiful and capable as the Bull & Stash Allison Portfolio. With an exterior made from top-grain leather - which will age beautifully the more you use it - this notebook features 50 replaceable perforated lined pages, has a clip-in pen carrier, and even has a host of pockets for business cards, credit cards, cash, or miscellaneous papers.
