Wallet for a 13 year old boy.

Tell me more about your needs (how many cards/ coin or not/ do you like the monogram or damier/ your budget).

I had a simple 6-card billfold wallet in monogram when I was your age.
 
Ah then I recommend the Florin Wallet (Monogram Canvas). It's one of the most spacious men wallet in monogram canvas, holds 8 cards plus coin compartment. Price is roughly 320 Euros.

Have a look on Vuitton.com
 
I had purchased this for my teen nephew. He's not a fan of monogram or damier. He's an artist and love colors, so the epi was a perfect fit. Good luck!
