These beautiful Vintage Copper finish soap dispenser pumps will complement any bathroom or kitchen! Rust proof – both the lid and pump are made from 304 stainless steel. Fits any Regular Mouth (2 3/8″ internal diameter) Mason jar. Use them to dispense hand soap, dish soap, lotion, hand sanitizer, or liquid hair care products. Includes one pump and one lid.
