Lets face it going into the toilet after someone else can be a perilous experience.
Let your family or housemates know when it safe to enter the bathroom – simply set this hand timer to one of 5 x 4 minute sectors.
Just gone for a pee, then set to All Clear.
Home from a big night, then turn to TOXIC and give those in your house a good 20 minutes before it’s safe to enter !!
