I bought these for my son - he lost all but one of his favorite mask lanyards and they were not available anymore so I couldn’t just reorder the same thing. I wanted just blue, since he likely wouldn’t use other colors. These have held up well, the clips are solid and the material seems strong. They are a bit on the short side, but work fine for us. I’d imagine they would be too short for an older child (they are fine for my tall 6 year old) or an adult.
