A personal sanitizer assembly for sanitizing a user's hands includes a bracelet that can be worn around a user's wrist and a holster that is coupled to the bracelet. A cartridge is provided that contains a fluid sanitizer and the cartridge is insertable into the holster. A pumping unit is insertable into the cartridge such that the pumping unit is in fluid communication with the fluid sanitizer contained in the cartridge. The pumping unit is actuatable into a pumping uniting condition to dispense a pre-determined volume of the fluid sanitizer when the pumping unit is actuated thereby facilitating the user to sanitize their hands.
