A pump to be used with our treatment serums, gels, cleansers and creams. The pump doses 1ml output per full compression and can be easily operated one handed. The serum pump can be locked into place without pushing it up or down, which means it can be relocked without wastage, making it ideal for travelling and handbag type use. We no longer supply pump tops as standard as the pumps are reusable which is better for the environment.The pump will need to be trimmed to fit your bottle and will need to be washed thoroughly, preferable with an antibacterial wash before being placed in to your bottle.
