What to know before buying

Listing details to confirm

Listing details are inconsistent: the theme is given as Fantasy and the colour variant as "150pcs-castle", while the feature text describes a Dark Magma theme. Two different size descriptions are supplied, so confirm the selected variant and dimensions before buying. Customer comments about small size make scale especially worth checking.
