I’ve owned innercircle before so it was nothing new. But i gotta say, people say the invisibility is like 9/10. But I’d say the invisibility is more like 5/10. I’d rather just buy mesika elastics. They are more invisible. If I use the loops pre-made, people will definitely see the string. But other than that, great product. It does have flexibility and strength. When you buy the loops though, don’t just start using them. Stretch them out first. Or else they will break and you will waste money quickly.
