CLOTHING

First, clothing is examined for quality of material and finish, thereafter measured to confirm accuracy of sizing, and to confirm that the item has not been altered or modified. Secondly, care labels are examined for composition of the item, then analysed under magnification for accuracy of text and font, to be compliant with the brand standards.

HANDBAGS

Firstly, dimensions are carefully measured on each handbag to confirm accuracy of the particular model within a brand. Then materials, serial codes and hardware are closely examined to confirm compliance with brand standards. Lastly, each item is examined under UV light to determine signs of recoloring on the leather or fabric and stitching.

SHOES

Shoes are measured to determine accurate sizing and examined in detail for the quality of structure and materials.

SUNGLASSES

All style reference numbers and brand font are examined under 10 x magnification to confirm quality, placement and accuracy of font.

JEWELLERY

Each piece of jewellry is examined under 15 x magnification to verify all text including brand, model, precious metal carat type, and all relevant assay marks.
