Hi-Density bowls are smaller than usual for the weight of the bowl. i.e. a 2lb 8oz Hi-Density bowl is the same size as a regular 2lb 6oz bowl. Supplied in pairs. This enables the bowler to play with a heavier bowl than they may otherwise be able to handle and also makes it easier to control the length of delivery on faster running greens. 2 full bias crown green bowls fitted with coloured mounts. Supplied in pairs. Available in Black or Brown.
