The term 'sparkly decoration' can be summarized as 'TINSEL, ' which is a type of decoration consisting of thin strips of shiny material, often made of plastic or metal, that are hung on Christmas trees and other objects to create a festive atmosphere. TINSEL is also used to decorate other holidays, such as Hanukkah and New Year's Eve. It is usually hung in loops or draped over objects to create a shimmering effect.
