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.

Our each is a package of (2) steel tech rulers. One is 6” x 1/32” for the first 2-1/2” then 1/64” for the next 1/2” then 1/16” for the last 3”. The other is 150mm x 0.5mm. Both have sliding markers/pocket clips, and both have mm:inch tables on the reverse side. You’ll need excellent eyesight.

From Helix®, this 18" long aluminum U.S. Standard triangular architects' ruler/scale has color-coded facings and is divided into 3. 1-1/2, 1, 3/4, 3/8, 3/16, 3/32, 1/2, 1/4 and 1/8 inch per foot. Yes, you can use it even if you're not an architect.

Vying for the Two-Really-Useful-Things-In-One Award, this 12-inch clear acrylic ruler is also a 2X magnifier! A red alignment strip runs right through the vaulted center of the ruler, which is 1-1/2” wide overall. The domed strip with the red line is about 3/4” wide. Also measures in Canadian, and at 12” long, that means 30cm.

No, these scales won’t tell you how much weight you’ve lost (you’re so disciplined!), but they will help you design something super-technical. Know why? ’Cause they’re architect’s and engineer’s scale rulers, from Helix, both (3)-sided in silver aluminum with color-coded sides. You pick: the architect’s with separate scales for 3", 1-1/2", 1", 3/4", 3/8", 3/16", 3/32" 1/2", 1/4" and 1/8" per foot, as well as a 12" ruler in 1/16" increments, all in U.S. standard; or the engineer’s, with 12", 1/10", 1/20", 1/30", 1/40", 1/50", 1/60" scales.
