The AliExpress listing is a functional equivalent in the scribing caliper category, not a confirmed identical product. No brand or retail price for the original was available to verify a direct match. The AliExpress unit shares the same tool type — a vernier-scale caliper with a carbide scriber for layout marking — but spec-for-spec confirmation was not possible from the available data.

Standard shipping from China on AliExpress runs 30-45 days for most destinations. Some AliExpress Choice sellers ship from EU or US warehouses, which reduces delivery to 10-15 days. Check the shipping tab on the listing before purchasing, and factor in customs clearance time if you are outside the US.

AliExpress Buyer Protection covers items that arrive damaged or not as described — open a dispute within the window specified at checkout (typically 15 days after delivery confirmation). Take photos of the packaging and the tool immediately on arrival. Because this listing has zero buyer reviews, documenting the condition carefully is especially important if you need to escalate a claim.

This scribing caliper is a fully manual, non-powered tool — no batteries are required. It uses a vernier scale with 0.1mm (1/128") resolution read directly off the engraved graduations, so there is no electronic display, no battery compartment, and no charging involved.

The AliExpress listing specifies 0.1mm and 1/128" resolution on the vernier scale across a 0-200mm range. Actual accuracy depends on manufacturing tolerances not disclosed in the listing. For woodworking layout and scribing tasks, 0.1mm resolution is generally sufficient; for precision metalwork requiring tighter tolerances, the lack of any calibration certificate is a concern.

The listing describes the tip as carbide, which is harder than standard steel and should hold an edge longer when scribing wood, laminate, or soft metal. However, carbide quality varies across manufacturers at this price point, and there are zero buyer reviews confirming long-term tip durability on this specific listing. The inclusion of a spare needle in the bundle suggests the seller anticipates tip wear or replacement needs.

The listing includes a carrying case, but no dimensions or material details are specified. For a 200mm caliper, a rigid or semi-rigid case helps protect the vernier scale faces and the carbide tip during storage and transport. Whether this case meets that standard cannot be confirmed without buyer feedback, which is currently unavailable.

The listing specifies both 0.1mm metric resolution and 1/128" imperial resolution, suggesting a dual-scale vernier. This is common on scribing calipers intended for general woodworking, where both measurement systems are used. Verify by examining the listing photos closely to confirm both scales are present on the physical jaw or beam.
