The packaging has a window on three sides so that customers can see the product. In the spaces indicated: (a) draw to a scale of 1:2 in fi rst angle projection, the PLAN and EV of the packaging; [10] (b) construct to the same scale, a one-piece development (net) of the packaging. Add a lid with three fold-in fl aps. Do not include a base; [11] (c) use sketches and notes to show a simple support, also made from thin card, which can be inserted into the packaging so that the base of the cosmetic product will be level with the bottom edge of the window.
