13 OS Mother Easer diapers. My son wore these for about 6 months last year before we transitioned to pocket diapers while EC'ing. 3 diapers are slightly bleached on the bottoms, one has a few more spots than the other two so I'm calling these three GUC. The rest are in EUC. These are cotton terry diapers and you can learn more about them on the Mother Ease website.
I am also selling a lot of 6 diaper covers through another listing here if you are interested!
