QandSweetBaby Boy Combed Cotton Socks Toddler Ankle Sock Non-Skid for Newborn Infant Childrens

Why does the warning say the "toy contains a small ball?" It's a sock. How can it not be suitable for children under 3 if it is being sold as a sock?

where are they made?

Are these too tight for a chubby baby?

Why does it say 100% cotton but then later says 82% cotton and other materials...
