All artwork is layered and organised in groups. You can add or edit the button according to your design needs, such as most of the colours, strokes etc. For this purpose, the layer effects used in styling the artwork are still editable.
The .psd files has the normal and the hover states of the buttons layered. You can add or remove buttons in order the menu bar to fit the dimensions of your project.
