Dinosaur design nap cover set, made of durable polyester. - Design: Dinosaur - Cover size: 80cm x 110cm - Material: 100% polyester Thank you for viewing. The fitted sheet cover is only used at the nursery, so this is unused. Although unused, it has been stored at home, so I will sell it to someone who doesn't mind that. It will be placed in an OPP bag and shipped via Yu-Packet.
