This is a used Font Fixation set of stamps. Only example stamping for the Font Fixation brand was done using this set. Some of those examples were on stainless steel. 
There is minimal, but some, light rust on the shanks of some of these stamps. There is no rust on the letter part of the stamp. The rust will not have any effect on the stamping impression. Font Fixation offers free rust removal on all stamps. Please contact them if you'd like to have these stamps cleaned up. 
This set is sold AS IS. 
It also includes an ammo box for storage. 
There are no quantity discounts or tier discounts, as this is from my personal inventory.
