The piano with the grade C or D is usually very old and tends to be lacking its gloss. It would need to be repaired especially for retailing. (It may be suitable for those who own workshops.)

The grade with the letter R (e.g.: RA+, RA-) means that the piano has been polished.

The piano with the grade A (i.e.: A+, A, and A-) can be highly glossy with our extra polishing.
