I have bought the pink ones like corina uses from murano millefiori. They have different sizes and colors as well and you don't have to buy them in a mix. I believe the design is called a cog. Here's the link that will bring you to their site and if you scroll down the page and there are a few different colors besides pink too. Hope this is what you were looking for!
