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. It helps to name the question the sample must answer: is this about part fit, shelf appeal, a licensed look or a target retail price? 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, the open carton or box and the contents laid out in one frame before anything is assembled. If the sample uses provisional packaging or a plain white box, identify that limitation in writing before review. Keep a reference list so a later production version is never approved against a different set of parts.
Review the whole building experience
Build the model using only the supplied instructions and check whether the parts list matches the contents. Note connection force on both assembly and disassembly, loose or over-tight joints, color consistency, sharp edges, model stability and the clarity of each numbered step. For tracks, assemble the full route and run the supplied marbles several times; for connector systems, test the connection format under normal child use. Record observations against the exact sample rather than turning one positive impression into a claim about the entire range.
Give every moving or powered feature a hands-on test
Battery-operated, pull-back, spray and motor-driven features need their own check beyond the static build. Fit the recommended batteries, run the feature through its full cycle and listen for strain or grinding. Confirm whether batteries are included, what the compartment markings say and whether the action works when the model is assembled as pictured. A function that works in a showroom clip should still work after shipping and after a child uses it repeatedly, which is why we treat it as a separate approval item.
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 with their own dates. A sample review does not replace the product-specific safety assessment, document review or production inspection agreed for the order, and it should never be recorded as a verbal yes that no one can find later.
Put the result in writing the same day
A useful approval record is short: item number and version, date, reviewer, the build result, the feature result, photos referenced, requested changes and the open questions. Written the same day, it captures details that memory flattens within a week. That record is what protects both sides if a later batch is compared to the sample, and it is the document a supplier should resolve against before production is released.
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, how it is stored and who holds a duplicate. Ask how substitutions or material changes will be raised for approval, and whether a retained reference, golden sample or pre-production review is needed for your project before the first bulk order is placed.
