This dispenser pump is made from high quality impact resistant plastic with a plastic dip tube that can be easily cut to length. Use this to complete your hand-crafted containers. Great way to dispense liquid soap and lotions. It's easy to add to any lid. Simply drill a 1/2" hole in your choice of container lid and attach the collar to the lid with glue. Then thread the pump onto the collar. By using this 2pc. pump you have the option of only removing the pump to refill the jar - not the entire jar lid.
