These are pretty good hair ties. Note that these are not the "big" size. They are probably the medium sized ones (NANO is the smallest). I was surprised when I got the VERY tiny box. Despite their size, they hold my hair very well (I have thin, straight hair). I like that after a day of wear its very loose looking but just leaving it alone till the next morning springs it back into its regular shape. To speed this up or have better tension on the loops, you can put it out in the sun or hot water. It still leaves traces in your hair - I think that will happen with any updo elastic. It doesn't pull much hair out when removing them. They are a little more frustrating the more you loop them around as the loops get caught on one another. Overall, better "elastic" than the regular ones.
