We choose our stock carefully so that they are all in good condition, but the cosmetic condition option for the camera is split into three different categories within this:
A "Near Mint +" camera will look almost new; it may have a few superficial signs of use or age (Top 1/3rd of stock).
A "Very Good" camera will also look nice but it will have more signs of wear such as worn down paint and small scratches on the metal (Middle 1/3rd of stock).
An "Average" camera will have more severe signs of wear/use such as deeper scratches, black specs and more obvious blemishes (Bottom 1/3rd of stock).
None of the cosmetic defects will have an impact on the mechanical working or functionality of the camera.
