Right off the bat, there are no instructions on washing these to make sure they retain functionality so if you don't know how to care for these items they're one use. The tightening knob is bulky. They do not stick to you as expected, while they are sticky as soon as I started tightening the drawstrings the edges started peeling off and unsticking from my body but maybe that's because when I opened the bag the "plastic film" that is supposed to protect the sticky side wasn't stuck down all the way. I got a two pack and only tried the black on, which is the one that didn't really work out. I bought this because I wanted a drawstring bra this style but didn't want to pay the price for a name brand one, I guess I should've. The product tag which was not fastened to the bra was stuck to the adhesive side so I had to peel it off. If I'm wearing a bra with no back and no straps I want it to stick right so I don't have to worry about it falling off mid day.
