The materials

Lead-free brass has been developed by manufacturers in recent years to eliminate the hazardous additive. The material is antimicrobial and naturally reduces the build up of harmful bacteria, which makes it suitable for use in sterile environments. Over time it will oxidise and develop a rich and deep patina known as verdigris — the original lustre can be revived with some metal polish, however we suggest enjoying the natural patina as it evolves with you.
