## Before you buy

- The listing's 1038-piece and LED claims appear in the title, while product details report a Number of Pieces of 1 and do not independently confirm LED inclusion. Age guidance also differs: the title says 7-14, the details say 14 years and up, and the age range is listed as Kid. The stated dimensions are 31 x 22.9 x 12 centimetres, while the separate size field gives 9.02 inches x 12.2 inches x 4.72 inches. Confirm the selected listing's piece count, lighting, age guidance and measurements before buying.

- Anyone relying on a specific age suitability, piece count or included LED without confirming the listing.

## Customer feedback
