I have a headcanon that Santa Claus, is a real wizard in the wizarding community, who for centuries, has gifted muggle children who are good each year with presents. He’s lived so long because he was the 1st to create the philosophers stone, (Nick was the only KNOWN maker), He uses the floo network, and a featherlight extension charm on his red bag, so he can carry limitless toys inside. Santa enchants his magic sleigh, which is flown by his reindeer. He uses a time turner to deliver in 24 hrs.

(headcanon accepted!)
