Seconds-GRED B items may have a scratch/line/mark through the back or somewhere on the base of the item; this is done in order to differentiate between First-GRED A quality and Seconds-GRED B quality.
What is the difference between a GRED A and a GRED B? All item is manually inspected and only pieces which pass the highest standards are classified as First-GRED A quality. An item is classified as a Seconds-GRED B where there is a marginal fault to the finish, the decoration or the shape. The fault is not structural, i.e. each piece still functions as intended and is usable.
Unfortunately, Seconds-GRED B CANNOT BE EXCHANGED.
