Because I had too many from the subscription service and they overflowed my storage space. I'm selling them at a low price! It's very economical because you just put a pad inside the diaper and only change the pad. I've tried various pads, and this is the best! It has high adhesion, high absorbency, and absorbs to the fullest! I'll stick with this from now on! Comes with leak-proof side gathers.
