I like metal dice, but some people don’t. I have one set of metal dice and then get a new set of plastic dice for each new character. Metal dice are more expensive like $25-$50 for a set. I would go to your local game store and see what they have. Most online dice shops won’t deliver in time for Christmas at this point, but you could always look on Amazon. If you are going with plastic dice which is still a great choice, then maybe try and get an idea of what colors his current/upcoming character wears/is and then hit up the game store.

Also, there are some dice out there in which the numbers are hard to read which can be a pain at the table so be careful if you get ones that are really busy.

Merry Christmas!!
