A useful distinction
A seller’s statement that an item looks unused does not identify its model or establish its history. Useful questions focus on the documentation needed to evaluate the actual product. Some categories involve requirements beyond a casual condition check.
Put it into practice
Ask for the exact product identifier, instructions and relevant history that the seller can genuinely provide. Consult official guidance for the category. If essential information is unavailable, keep the uncertainty visible instead of replacing it with a promise based on appearance.
