Resin

Each shaker is carefully made with quality resin (either UV resin or epoxy resin).  Each shaker is decorated with various embellishments such as glitter, inclusions, mini clay pieces, etc.  Some shakers are "dry" (no liquid) or some may have liquid.  If the shaker is filled with liquid, you will notice an "air bubble."  This allows some room for the inclusions to move around.
