Pacifier can be attached at the green, looped end while the durable heart clasp can be used to fasten to your baby's cloth. Multiple coats of natural, water-based, non-toxic lacquers ensure this pacifier chain's colors will stay vivid and bright for years to come. A quality toy that was crafted to withstand years, even generations, of childhood adoration and play. Never attach chain to ribbons, laces, or other loose part of clothing
