Actually, this kind of thing is simple. A person's budget of 500 is already a lot. So you don't have to worry, and the best way is to treat your nephews equally, no matter who is older or younger, and buy them the same thing, whether it's a dress, a pair of shoes, a hand, a plush toy or an assembled toy.

In my experience, I have sent some toys to the younger generation, especially Lego-like assembled toys, which are tens of dollars cheaper and hundreds of dollars more expensive.

You can buy them all kinds of toys according to their size, so that they can fight together, play together or get an assembled toy after the game because of different styles. If they are not together, they can also be assembled separately. Anyway, everyone's toy prices are similar, so there should be no dissatisfaction. This is a particularly meaningful thing.

Finally, I want to say that when you choose these assembled toys, you can choose themes according to their hobbies, such as pirates, hospitals, manors and so on.
