The heavy, solidly-plated object is actually a simple Filipino shell. The lustrous finish, however, is a result of four stages of dipping: first in plastic, then in copper, then in nickel, then finally in sterling silver.
After that, a sealant to prevent tarnish is applied. The finish will last for many years to come -- hopefully also your enjoyment of them.
Sold in a gift box of 6 or of 12 shells, the box is hand woven for Caro Wilson in Bicol, in a twist-on-twist pattern, out of Karagumoy, -- a tall-leaf pandan with a thorny spine. Once the thorns are removed, the density of the leaf makes a very fine, long lasting plant material for weaving. Dimension of the box: 5" x 5"x 3" (13 x 13 x 7.6 cm).
