Quality & grading

Visual Grading + Functional Testing Buyers Can Verify

Grade names alone are not enough. We explain the cosmetic expectation, test the device functions and agree on evidence before shipment.

What A+, A and B mean in practical buying terms

Important: the photos are real Moleen stock/workflow images and show the surfaces we inspect; they are not a promise that every phone visible in each photo is the named grade. Actual batch condition is confirmed against the agreed grading criteria.
Functional QC

A simple inspection flow buyers can audit

Identity & systemModel, storage, activation/lock status as agreed.

Diagnostic evidence

PhoneCheck reporting can be added when the order requires it

Some buyers need a standardized diagnostic report in addition to our physical and functional checks. Confirm the reporting requirement before quotation so the cost and workflow can be included.

Real work environment, not a stock-photo laboratory

Our site intentionally shows the actual working environment. For a B2B buyer, a realistic view of the people, inventory and testing process is more useful than an idealized factory render.
