I just received these through the post today and was really surprised how beautiful the illustration were, its for my little girl who is almost 3, but I have a 1 year old and he attacked them straight away and has bent a few already, it is really really thin and flimsy, I think I will have to go invest in some stickyback paper to maintain them. I expected them to be more sturdy, even hardback because of the price is a bit higher than several other flash cards but the illustrations are really nice
