What is a black book? Generally, it’s a collection of dirty little secrets – or phone numbers – that are for your eyes only. Unlike James Bond, we do things a little different here at Cool Material. We compiled a list of the greatest web stores on the Internet. The sites where we get our gear, gadgets, watches, wallets, and just about anything else we interact with on a daily basis. Now that our black black is done (for now at least, these things have a way of changing) we’re going to give away the keys to the kingdom. The Black Book is Cool Material’s guide to shopping on the Internet and now you get it for free. Shop no further.
