Santa costume gloves was removed from RuneScape after an update, but still exists in-game for those who had obtained it.
The Santa costume gloves are part of the Santa suit obtained from the 2008 Christmas Event. They are unobtainable for players who did not complete this event. Players who have lost the gloves and want them back can go to Diango in Draynor Village, who will replace any lost event items for free.
During the 15 Days of Christmas in 2013, this item, along with other Christmas-themed equipment, were given the hybrid style of combat, and stats that scaled with the player's levels. This was so players could use these items in combat to assist in hunting for festive crackers during the event.
