sealskin
A light, tough leather of very fine quality and
distinctive appearance, with excellent wearing
qualities, produced from the skins of various
species of seals. It may be finished with its own
delicate grain pattern and lustrous surface, or
with a bold grain produced by a combination of
embossing and boarding. While customarily black it
is also produced in colors. Although its use as a
covering material for books goes back hundreds of
years, it is little used today because of the
declining number of seals, and the excessive
oiliness of the skin. See also:FLESHER ; PIN SEAL (1) . (83 , 295 )
