For over 70 years, Libbey's proven commitment to quality has been backed by our well-known guarantee, "a new glass if the rim of a Safedge® glass chips." If the rim of any glass covered by the Safedge® guarantee chips, Libbey will replace or refund the price of the glass when it is returned to the dealer/distributor from whom it was originally purchased. Of course this guarantee does not cover breakage.
