These are long fingernails with blue butterfly nail art. Four additional materials can be found in the Materials section of User Contributed Assets. I have included a spec map so the tops are shiny and the undersides dull, like natural or sculptured nails usually are. Each nail is 100 faces, so they look best with a subdivision surface of two or three. I have updated the mhclo and obj files so the fingernails should work on both hands now.
