Shirts are made from cotton‑based knits (examples include 100% cotton and an 80% cotton/20% polyester blend). Figures and buildable toys are made from plastic.
Shirts are described as soft and durable with sizing guidance. Some listings say they fit true to size (one notes sizes for ages 2–14), while another notes sizing can run small. Care instructions recommend machine washing and either tumble drying or line/lay‑flat drying.
