Marble Runs: FAQ

How do I ensure the pieces fit my existing sets?

Check the connector diameter in the product description. Most AliExpress sets are compatible with major global brands, but verifying the specific 'mm' size in the technical specs ensures a perfect fit.

How can I verify the safety of the plastic materials?

Look for 'ABS Plastic' in the specifications, as it is non-toxic and highly durable. High-quality listings will often display EN71 or CE certification images within the product gallery.

What indicates a high-quality marble run set?

Check the wall thickness of the tubes and the stability of the base pieces. Weighted bases and snap-lock connectors are key indicators that prevent the structure from collapsing during play.

Will the pieces arrive intact if the set is bulky?

Opt for sellers offering 'AliExpress Selection Standard' shipping for superior protective packaging. Bulky sets are usually double-boxed, but checking recent photo reviews confirms the packaging quality.

Look for 'Universal Fit' descriptions if you plan to combine the set with other building block brands to create larger custom structures.
