To be honest I use them for ear loops on face masks. I used 2mm but can't find it anywhere now. I avoided 4mm as they are too thick. They should be 3mm but they are definitely 4mm. Either way, it's excellent value for money. They're a little more resilient than I'd like, but you have to do what you have to do in these trying times.
