The Pocket Engineer - Wallet Ruler and Conversion Reference

love it!

used it during a recent final exam and it helped a bunch! design and construction is excellent and my fav feature so far is the quick reference prefix sci conversions

Solid

Great quality and a really cool idea; information could be a bit more organized though, especially on the back.

"O-Chem Stencil"....use it with your Pencil

As a high school teacher of more than 30 years, I can attest for the declining state of penmanship and general use of writing implements. If this generation has any hope of drawing legible, usable, dare I say, "beautiful" organic structures then that 'hope' lies with the incredibly useful "Pocket Chemist" tool/template. I buy a class set every year for my small group of chemistry nerds and send them off to college fully prepared to not embarrass themselves in organic chemistry. This product is just that good! So divert some of that science budget away from Elephant's toothpaste and spend it on something with staying power like the Chemist Stencil.
