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.

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.

Says so right on the packaging. Measures (pun intended) 18” long x 1-1/2” wide. Has 1/32” increments for the first inch, then 1/16” on one edge and 0-45cm in 1mm increments on the other. Made in England of blue-tinted translucent plastic. (There is no legal penalty for using it at home or in a school.)

Accept no amateur rulers. But seriously, this 24-inch professional steel ruler from Helix® is cork-backed, and marked in 1/32” increments for the first two inches, 1/64” for the third, and 1/16” for the rest. Also shows 60cm x 0.5mm for the first 10cm, and 1mm for the remainder. Markings are etched, so they won’t rub off with use.

There are just two, actually, and one of them is a pencil, on a drafting compass. Sometimes it’s better to draw circles without using software, don’t you think? If so, try this one from Helix®, with 3-1/2” legs with (2) 2mm dia x 15mm long leads, a small sharpener, folding needle guard (for the other point) and a 3/8” ID pen/pencil holder with a thumbscrew lock. Made in France, merci.

This 18-inch x 1-1/2” wide clear acrylic office ruler from Helix® is marked as an office ruler, and we don’t know why, but we like it. Measures in 1/16” increments, and all the way up to 460mm on the other side. Edges are cut at 45 degrees for your non-smearing, line-drawing pleasure.
