What this product is

The useful part of a digital angle finder is the zero that still reads true after the arms have been folded into a carton. Typical talks put the bare tool in an estimated band of about 6 to 13 dollars after a 300-piece opener, next to an indicative retail window of 24 to 42 dollars. Potential trouble sits in the pivot. A unit can read square on the bench and then shift once the hinge screw is locked for transit. Record 0, 45, and 90 degrees on a known square before and after a carton drop, and freeze a written tolerance before a larger lot. Backlight strength and battery-door fit differ by cavity. A first order usually changes a logo pad, a shell color, and an insert card. Destination battery marks sit outside this unit band.

Indicative sourcing numbers

These are desk estimates for a conversation, not a factory invoice and not a retail offer from this website.

Indicative China sourcing price: $6 to $13
Suggested retail range: $24 to $42
Estimated gross margin: 30% to 48%

Indicative estimates only. Actual margins vary by supplier, quantity, specifications, shipping, duties, taxes, marketplace fees, advertising and destination market.

Why it is interesting

Export plants already hinge metal arms to a small display, so a buyer can compare zeros instead of funding a new gauge.
Branding stays on color, a pad print, and the insert, which keeps the first lot closer to a running platform.

What to specify

Form: Two metal arms with a digital head
Readout: LCD degree display; confirm resolution on the sample
Check points: Buyer-set tolerance at 0, 45, and 90 degrees
Power: Small cell in the head; confirm type on the sample
Finish: Stainless or painted arms, plus an optional case

Customization and private label

A logo pad, shell color, and a printed insert are the usual first-order changes; a private display program is a separate quote.

Some customization is realistic on this kind of product. Private label packaging is often possible once artwork is approved. Read how private label manufacturing in China is handled, and when a new product needs the OEM/ODM path.

How the desk would source it

Note 1. Log angle readings before and after the hinge screw is tightened for packing, and reject a lot that walks off the agreed square.
Note 2. Photograph the battery door and the folded carton fit so a swollen clip is caught before freight.

The usual path is the same as other China factory sourcing: confirm the spec, compare factories, sample, then inspect before shipment. China supplier verification and China quality inspection are available. Goods can be received at the Xiamen warehouse and moved through China warehouse consolidation or sea, air, and express freight.
