Our Notables Fine Stationery is printed on heavy 140lb natural white stock, for those who prefer our most fine and elegant flat notes. Choose between Script, Engraved initials, Copperplate initials/name, or Monogram. See thumbnails for examples of each. The signature warm slate grey color for personalization comes with matching slate grey envelopes. All other personalization colors will come with natural white envelopes. (Please note: The signature slate grey is not as blue as it appears in the individual examples shown. The photograph shows a better representation of the slate grey color.)
