Firstly, when you see the word "assortment" it means that you are only purchasing ONE product at a time, NOT a set. So while the image may have 3 baubles, the purchase will only be of one unless you buy more than one.
When a product is an "assortment of..." this means that there are more than one type, usually a different shape in the same range. We cannot guarantee the shape that will be sent to you but please contact the store to enquire as to whether we can accommodate your request.
