Book marks engraved stainless steel. This beautiful set of five bookmarks are individually Engraved. They each have a separate saying yet they are part of a whole. This would be a great gift for four of your best friends or family members. They are made from up cycled muffler pipe. Each piece is pounded flat and then engraved. The hearts interlock with each one of the others almost like a puzzle, sort of like family interlocking with each other.
