December 24 – Kertasníkir (Candle-Stealer)
The thirteenth of the Yule Lads comes on the night before the 24th of December and departs for home on the last day of Christmas or the 6th of January. He was known for being the one who followed children to steal their candles (which used to be edible, made from fat).
Kids often put one candle for him in their shoe that is in the window and get some extra treat from him in reward.
