This is how I never lose my boat key. The attached flotation device would float if it fell in the water. I haven’t tested this function yet. I don’t plan to either I just trust in the logic of it. In my handbag it is so huge it doesn’t fit anywhere well. The colour is bright and so even in the darkest corner of my handbag it will always shine.
I just need to remember to bring it with me.
I almost forgot it this morning. It was the last item to pick up before running out the door.
What is attached to your boat key?
