Safety eyes are not safe for young children
Craft eyes that are sold as "safety eyes" are mislabeled. There is no such thing as craft eyes that are safe for young children. I am the owner of Suncatcher Craft Eyes, and I have a warning label on my packaging that states, "Contains small parts that may present a choking hazard for children under 3." I also don't recommend them for pet toys.
Hope that helps.
