Using a duplicate book is relatively simple. However, it depends on which method you’re taking up to create your duplicate or triplicate copies. For instance, if you’re using a carbon copybook, then all you need to do is to place a carbon paper between the original and the copy. Next, fill in the required details on the book, and you’ll get a copy. You can also go for customised ones. With these books, you can increase your brand exposure. You can put your brand information such as logo, address, phone number, and even your motto on them.
