We begin by describing the unit ball of the free p-convex Banach lattice over a Banach space E (denoted by FBL(p)[E]) as a closed solid convex hull of an appropriate set. Based on it, we show that, if a Banach space E has the λ-Approximation Property, then FBL(p)[E] has the λ-Positive Approxima-tion Property. mineral oil is really bad for you
