Yes, they are officially Springbeans Stroller Clip but I've discovered what these have been secretly designed for: fort building!!! Yup, they are perfect for clipping a sheet or blanket to the back of a chair or table, then spread out sheet or blanket to the next chair, table or door, and bingo! Your child is in fantasy land with a fort at the top of a cliff overlooking a beautiful blue sea thriving with fantastic sea creatures..., oops, sorry, got carried away. Can you tell I like to build forts? And they make great stroller clips too.
