Hello,
Yes, these are sold individually, so one per package for the price that is listed. The colors that we have available are listed there as well and they are White and Ivory.
As for the design. A free design comes with the bookmark but we don't have any say in what design comes with the bookmark. They are put together by the manufacturer and then sent to us so we do not know what free design comes with the bookmark until we get them in. The photo we have on our website is from our distributor. Hope this information helps :)
