Quality assurance is stated, although finished products are checked by packing staff, and no written corrective-action or complaint-handling procedures are reported. The supplier has no stated inventory, overseas warehouse, or overseas showroom capability. No Fortune 500 cooperation is reported, and the available financial figures are not sufficient for assessment.
