The band of the belt was made of dark leather with a metal buckle.
The belt was worn by Credence Barebone in 1926. His adoptive mother Mary Lou Barebone used this belt to punish Credence. A witch named Porpentina Goldstein attended one of the Second Salemers meeting in the Second Salem Church and saw in front of other people how Credence got punished by his mother with the belt. Tina then magically let the belt flew away from Mary Lou her hand, to save Credence from that beating.
On 7 December, his mother caught Credence and Modesty with a toy wand that Credence was holding in his hands. When Mary Lou was ready to punish Credence with the belt, the belt was magically torn from Mary Lou's hand and it flew into a far corner. By the force of the movement of the belt, it caused cuts and marks on her hand, the same injuries Credence had. When Mary attmpted to pick it up again, the belt magically moved on the floor away from her, before she was killed by an obscurus.
