Our market is regularly filled up with our surplus production of both standard and custom products, as well as prototypes and experiments from our development work. They are combined in sets; some are seconds with small faults while others are in perfect condition. The more seconds, the lower the price.

Typical errors are spots in the surface (that do not affect function). Another typical error is that the plates might be slightly wobbly on our superstraight sorting tables.

What you see is what you get - all items in the set are shown in the photo. There is only one of each set, and all sets are ready to be shipped. Photos do not show sizes, please check the diameter in the set name.
