Very, very practical.used with a strong wind did not move,,,,,
Everything is perfect!
I bought these number magnets because I do Trails (mountain running) and I was looking for something that would not damage my clothes (like pins), despite the fact that the arms move a lot and the branches that could be in my way the magnets did not move an inch! After the race my shirt was not damaged and I was able to put on and take off my bib very quickly. This will be my new bib holder from now on. I recommend
Quality product and services that meet my expectations. Do the job very well!
