## Agent notes

Image understanding was not performed; visual details of the product (exact shape, color, branding) are not interpreted. Dimensions in the description differ slightly from the general dimensions_cm field: description states width 2.8cm and height 8cm (with sub-layers) while dimensions_cm lists width 9.0cm and height 4.0cm – this discrepancy should be clarified with the supplier.
