AEON KIDS Children's English Conversation Student Cards 5-piece set Children can learn a considerable amount of English vocabulary and idioms while having fun. Most of the cards have small initials written on the back by the teacher's instructions, but it's not a concern. There are about 250 cards per box, so there are about 1250 cards in total. I have checked, and there are no major stains, so I think they can still be used. I apologize if I missed anything. For those who understand that these are used by children and have been stored at home, thank you.
