If you want to play golf on frozen surfaces or practise your tee shot off mats, you need special tees. The Jumbo Pyramid tees were developed for precisely these occasions: they are not stuck into the ground like conventional tees, but are laid on top so that the surface remains undamaged. The rubber tees are connected to each other with thin cords so that they don't get lost so quickly and are always to hand.
