We are always loosing them! They end up everywhere but we can never find one when we need it, no matter where we go there will always be someone asking if anyone has a clip they could borrow. I am always searching through the bottom of my bag trying to find them! So I found an old tic tac box (which is bigger than the usual boxes...?) and filled it with clips and hair elastics so now I always know where they are!
simple but effective and you only have to buy some tic tacs!
