Range varies: some items are ready‑to‑play dolls or figures, while many are buildable sets. Piece counts across listings run from as few as about 31 pieces up to roughly 630 pieces, so assembly can be minimal or substantial depending on the set.
Several listings include CPSC small‑parts/choking‑hazard warnings for children under a specified age. A few also call out choking risks from small balls or tiny accessories. Always read the product’s safety warnings and age recommendations before giving to a child.
