I have used Proraso soap (that of the green tub) for a while and it is one of my favorite soaps. As a result I just brought a tub as a gift for my father. Previously when I have purchased it the soap fits in the tub snugly, right up to the edges, but the one I just got has a gap round the edge. Should I push the soap to the edges of the tub to stop water from getting behind the tub or will it work the way it is?

Thanks,

Harry
