In our product development process, when we look at ways of ensuring hygiene and preventing our products from leaking, safety and quality are always our top priorities. Unfortunately, there is always a residual risk in this area with pump dispensers. This risk is currently too high for our standards. We do use a pump dispenser with our slightly thicker pjur TOY LUBE and this has proven to be a good solution for this product. However, we have not been able to use this type of closure with our less viscous pjur products due to the consistency of their formulas.
