Start with the object that must fit.
- Measure the item you intend to carry, including its case if relevant.
- Check the opening and usable interior dimensions, not only the outer width and height.
- Ask about dividers, lining, curved corners and closure clearance that can reduce usable space.
- Confirm the strap length or drop, whether it adjusts, and which accessories belong to the selected option.
Request views that answer functional questions.
An open interior, the closure, strap attachment points and an image with a ruler can resolve different questions. Ask for the missing view instead of treating many exterior photos as complete evidence.
A photograph cannot establish leather type, load capacity, hardware life or authenticity. Do not infer those properties from a brand label.
Compare packing choices.
Ask how the bag will be protected and whether the proposed packing compresses or folds it. The effect on dimensions and shipping cost depends on the actual package and current route.
Keep protection needs separate from price. Removing protective packaging may change risk even when the quote becomes lower.
Questions at this step.
Will a laptop fit if the outside width is larger?
Not necessarily. The opening, lining, compartments and closure can reduce usable space. Compare the laptop with usable interior measurements.
Does a material label prove composition?
No. A label is a claim shown in a photo. It is not independent material testing.
