It’s a cornucopia of stencils. All shapes, no alphabets. You’ll get a profusion of (8) clear acrylic stencil sheets, including: a raft of ovals; a preponderance of squares; a farrago of circles, hexagons, pentagons and triangles; a collection of a bunch of shapes, including trapezoids; a roomful of interior design shapes; a melange of electronic symbols; and an assortment we can’t altogether identify, but might be for printed circuit design. All have mm rules along at least one edge.
