Muy comodos y utiles ,los volveria a comprarThese Are CHILDREN size lanyards NOT ADULT SIZE I WISH I WOULD HAVE READ THE REVIEWS BEFORE BUYING NOW I HAVE TO SEND THEM BACK.It was goodSuch a weird world we're living in that I am buying lanyard straps for my son's masks to go back to school. The product arrived next day, as expected and easy to get on/off the masks. They aren't too heavy that it weighs the mask down on my 5 y/o.Helps me keep my mask in place and I don't worry about leaving it in the car when shopping because it hangs around the neck.Was greatPerfect for keeping my mask with me at all times. I especially love it when I’m at the exercise club. It is on me when I walk from one piece of equipment to the other and then I can take my mask down when I’m actually on the equipment.My son needs to wear a mask for in-person school a few days a week. Now that I put the lanyards on his masks he isn't losing them anymore!
