Dalek soap
From Tardis Wiki, the free Doctor Who reference
In Earth-33⅓, Dalek soaps, along with Dalek slippers and loo rolls, were some of the Who merchandise that the Master travelled back to 1964 to purchase at pre-inflation prices to sell at a later date. According to the Sixth Doctor, this transgression of the First Law of Time resulted in the Master's banishment from Gallifrey. (COMIC: Doctor Who? 107 [+]Loading...["Doctor Who?
