Packaging and content were OK and delivered in 97 Days during COVID-19 crisis. HOWEVER, description is misleading : There is not four prisms but only one piece⁽¹⁾ with a square base. (1) Technically, this is not a prism since the mains edges are not parallel but this point is not a problem, since the pictures do no leave any doubt on that point.
