No Brand sponge dental floss

This is No Brand's sponge floss. I've seen a lot of people using sponge floss lately, so I bought it since No Brand happened to have it. I guess sponge floss cleans better because the threads swell up when you use it? But I'm not sure if sponge floss is bad in general or if the No Brand brand is just bad; anyway, I didn't like it. Once I finish this, I plan to go back to the floss I usually use.
