I opened a bag of wellness superios that I'd had stored in a large plastic Rubbermaid box for some time.
Found this diaper in the middle of the bag that appears to have mold growing in between the thick clear plastic landing strip and the white plastic diaper backing.
I doubt they got wet in my storage - this one was in the middle of the bag and no others were affected. Also - no other diapers in that whole plastic bin show signs of water damage. My guess is that something weird happened in manufacturing.
Just wanted to share the oddity.
