these are the softcup things.
you can leave these things in for 12 hours. they are so cool. Since I haven't even had mine in for 12 hours, I guess it just catches all the blood in the plastic cup part, which is really thin plastic, it reminds me of sandwich bags, only texturized a little bit, & dump out the blood & throw it away.
ew. gross. I just wanted to try it because, well, its something new to me. My Mom used to use them when I was a kid though, I remember I wanted to try one, but she said I was too young. PSSH. I WILL BUY MY OWN NOW, THANK YOU.
