I use the plastic eggs and stuff them partly for weight and partly to give them strength if a toddler steps on them. I tape them shut as they are just for hunting. They get hidden and found many times during Easter season - and we often take till end of May to find the last stray eggs that have found their way somewhere we didn't look. Good news is this is a one time purchase that is reused year after year and the kids love it. They will hide them for each other to find.
