> Replace an unsupported solid-wood claim with observable details. Keep the buyer's material question open and plan photographs that answer what they can.

Original explanatory diagram. Keep the stated item, supplied measurements and observed condition together. A photograph does not establish an unseen specification.

If an item's material is unknown, say what you can observe and leave the material unconfirmed. A wood-like surface, a color or a photograph does not automatically establish solid wood, veneer, a manufacturer or a particular species.

This fictional storage-unit example demonstrates the difference between an observation and a claim. It is not an appraisal or a material-identification guide.

## The draft and the evidence

The original draft says “Solid oak storage unit, vintage, excellent condition.” The supplied facts are narrower: a brown surface, two doors, one removable shelf, measurements of 80 cm wide × 35 cm deep × 90 cm high, and a small chip along the back edge. The seller asks $45 and offers ground-floor collection at an agreed time. No label, material specification or purchase date is available.

“Solid oak” and “vintage” are unsupported in this example. Removing them loses no verified fact. The chip should remain visible in the description even though it is on the back. The measurements can stay, with the correct order and units.

## The finished draft

> **Two-door storage unit, 80 cm wide — $45**
>
> Brown storage unit with two doors and one removable shelf. Seller's measurements: 80 cm wide × 35 cm deep × 90 cm high.
>
> A small chip is visible along the back edge. Material, manufacturer and age are not confirmed. The listing does not claim solid wood.
>
> Asking $45 for the unit with its shelf. Ground-floor collection at an agreed time; please confirm the arrangement before travelling.

This is a complete fictional text draft, not a live sale offer. It leaves the material and age unknown while retaining the seller's stated price and collection arrangement. Before publishing your own version, add actual photos of the front, inside and chipped edge. This demonstration does not include photographs or a verified material finding.

## Improve the evidence without overstating it

An actual readable label may help identify a manufacturer or specification. Preserve its exact wording and check that it belongs to this item. A photo of an unmarked underside does not resolve the material question. If no reliable information is available, the honest unconfirmed statement can remain in the final description.

[eBay requires listing descriptions and product details to match the item](https://www.ebay.com/help/policies/listing-policies/item-description-policy?id=4372). That is a useful illustration of why unknown material should not be filled with an appealing guess. It does not mean this example has been reviewed by a marketplace.

[Check your own listing](https://makethisuseful.com/start/listing-grader). Choose each checklist answer yourself and enter only wording you can support as Recorded. The tool preserves your wording; it does not identify material or remove unsupported claims automatically. Keep the next evidence question separate from the buyer-facing description.
