Toys means different things at different age. When my boy was a baby, toys to him was just rattlers and soft toys. Now that he is seven, toys to him are those scientific experiments and puzzles.
Meanwhile, toys are always an attraction to boys. My older sons still like to visit those shops selling action figurines and collect those rare and very expensive limited versions of their favourite action figurines.
They insisted that these will become very good investment in future and they can sell those action figures off for very high price. I doubt so but if they use their own money to buy, why not?
