Start with the decision you need to make
Send the supplier item number, intended selling market, estimated order quantity and the versions you want to compare. State whether you are reviewing the build itself, the retail presentation or a proposed packaging change. Sample availability, cost and dispatch arrangements need confirmation for the selected items; a catalog image is not a sample reservation.
Identify exactly what arrives
Record the item number, piece assortment, colors, instruction language and packaging version when the sample arrives. Photograph the unopened pack and the contents. If the sample uses provisional packaging, identify that limitation before review. Keep a reference list so a later production version is not approved against a different set.
Review the whole building experience
Build the model using the supplied instructions and check whether the parts list matches the contents. Note connection fit, loose components, model stability and the clarity of each step. For tracks, review the assembled route; for connector systems, review the connection format. Record observations against the exact sample rather than turning one positive impression into a claim about the entire range.
Separate approval from open issues
Use a dated review with three outcomes: accepted points, requested changes and unresolved questions. Packaging artwork, labeling and market documentation can remain separate approval items. A sample review does not replace the product-specific safety assessment, document review or production inspection agreed for the order.
Make the approved version usable for production
Link the approval record to the supplier SKU, your retail SKU if available, packaging revision and order reference. Confirm which physical sample or signed specification controls the order. Ask how substitutions or changes will be raised for approval, and whether a retained reference or pre-production review is needed for your project.
