refer to picture:

The picture is of an anti theft product that fits onto the tops of bottles of spirits or wine .It is reusable.These are supposed to be impossible to remove when in place.This is wrong as i removed it myself just by pulling and twisting it.It took about 1.5 minutes to remove it from the bottle.You get these in most supermarkets and shops.It is comparable to tearing a tel directory in half but not as difficult.I dont know how you are "supposed " to remove them and no i havent been shoplifting.
