In the "Masasuke Shozoku Sho" (Masasuke's rule book on costumes), an article explaining about furnishings at the hisashi (a long, thin hallway which surrounded the main wing of an aristocrat's home, in traditional Heian architecture) describes about a two-story shelf, 'on the shelf, there is a platform on which yusurutsuki is placed. There is a brocade and the lid of the yusuritsuki on the shelf, and all of them are made by gold."
