This is a standard set including only the above buttons. If you would like to mix and match your own set, check out my Mix & Match listings here: http://www.etsy.com/shop/primpmyblog?section_id=11857514
You may choose any one of the five listed shapes. Buttons have a transparent background, are 40 x 40 px (unless otherwise specified), and will be delivered in PNG format via email. I will also provide you with the information needed to properly install and link them yourself. I will help you until your buttons are up and functioning!
If you would like to purchase buttons in another shape, color, or pattern, or if you need a button for a social network not listed here, please convo me about a custom listing - I would love to work with you to create buttons for your needs!
