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.

Our coolest ruler, hands down. It’s dark blue plastic, T-shaped, and packed with information. It’s an American Wire Gauge and a screw-size gauge. It measures UTS and ISO screw pitch, has SMD capacitor info, conversion scales, transistor and diode diagrams. It has a list of SI prefixes, digital logic gates, logic identities, electrical units and abbreviations, colors and wavelengths, transmission line equations, a protractor, a breadboard and tons more. If you’re not into that stuff, use it a 13”/33cm ruler. Measures 15" x 6-1/4” x 1/16" overall, and you might need a magnifier to read some of it. Made in the USA.

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.
