These squares are beautifully machined from S50C carbon tool steel. They are shipped from the factory with a protective layer of oil applied. While this needs to be removed before use, we recommend storing the squares in its box or in a location where it can't accumulate dust. If left unprotected for long periods of time, these squares may be susceptible to rust - though none of ours have yet been affected in our workshop.
