If you still use bobby pins I found a great way to store them! An empty Tic Tac container is the perfect size for them. I took the whole lid off of one and put the pins in. Be careful not to over fill it though because the sides of the lid fit into the clear plastic container and you need room for it to fit in.
I usually keep a box of Tic Tac's in the car for 'emergency' breath freshener especially since I eat in the car often. A card of 45 pins will fit in with a lot of shaking. I don't use bobby pins but I had a card of 45 pins for Y3K just in case...
