lace your favourite chocolate and sweets or your packet of ciggies inside the jar and screw the lid closed. Programme the timer; you will see the clock count down until it is time for your treat. To open the jar squeeze the pads on top of the lid and twist anticlockwise, but remember if you do this before the time is up you are in for a shock literally. Once the timer is set you cannot get into the jar until the time has passed and if you do you will receive a rather deserved shock A great idea for dieters or those trying to quit the fags or for keeping other members of your household away from your stash.
