I used these for seniors at my work.Bought a bunch of these not for ID badges, but to attach Cyalume glow sticks for an outdoor evening event. Easy way to keep track of those in your group at night and helps with safety. Not all lanyards work for this purpose, as some have small attachment clips.About 1/2 of my lanyards broke by the end of the first week of school.? I teach second grade so they’re 7-8 years old, but I’m disappointed they fell apart so quickly.Needed a bunch for lots of people and the quality and prices was great. They work very well and seem to be sturdy enough to last for a long time.Light and durableThese lanyards are easy to see and use and seem to be durably made. While they are too big for smaller children, a knot will shorten them quickly and easily. They are great for emergency whistles, flashlights, name tags, etc. I have not found any negative yet. I put a cheap emergency whistle on most of them and donate them to a seniors center for bingo prizes. They are greatly appreciated.Unknown how sturdy the swivel mechanism will hold up. I'm using lanyards to hold key chain. Product seems to fit the purpose.Fair to good quality but only 40 lanyards were in the bag. Advertised and sold as 100 lanyards; important event with 75 needed and only 40 total. Buyer beware
