Built on a history of over 130 years of American craftsmanship, Boos Block surfaces fill your kitchen with timeless tradition in countertop appearance while maintaining a natural food safe element for food preparation. Ultra premium countertops are manufactured with full length continuous rails from our choice selections of American hardwoods. Standard models ship with our oil finish. Optional finish: varnique conversion varnish. Care and maintenance: soap and water clean-up. Revitalize with our Boos Block Mystery Oil a minimum of once a month (depending upon the use and household conditions). Use our Boos Block Board Cream to seal the surface after oiling.
