Well the obvious answer is Amazon since acrylic bookmarks are such a flooded craft idea, like here is 100 for $22. I also searched koozies and there are tons of bulk pack options. You can try places like jpplus.com, conde.com, coastalbusiness.com, and I am pretty sure you can order custom shapes from custommadebetter.com
