Hooks in back.
I thought this was too short, as I meant to buy a lanyard that would hold an extra mask in front and have one on the mask I am wearing. Working at a school, I will need to switch masks quickly if one becomes moist. These hook around back.  It is my fault for not looking at the description and all the pictures.  I am keeping them though since I think these will be good when ears get sore from the mask wearing.
