Because Pit Putty does what is says on the tin (literally), once somebody starts using Pit Putty, they very often will continue to purchase every second month. As well as being super effective, Pit Putty is also safe to use, as its free from suspected carcinogens, such as aluminium oxides and preservatives. Although inconclusive, recognised studies have suggested that these additives could lead to breast cancer. We’re taking no chances! So no harmful chemicals are used in Pit Putty’s production.
