Our single pack comes with one glass base and one copper alloy pump top (not copper colored). All pumps come silver-polished. These are for 90% and above isopropyl alcohol, ethyl or distilled water use only. All of our pumps are hand-inspected three times prior to leaving for their destination. Quality over quantity is what we love. We recommend that no one use Dark Crystal Cleaner Solution in our pumps - it will corrode the copper pumps unless proper washing of the V3 pump is done weekly.
