Review on Master Organic Chemistry with The Pocket Chemist Exam Edition: A Stencil Drawing Template by Summer Hendricks

Just take a look at this caffeine molecule before and after. If you just want to use it for drawing I recommend the exam version as it comes with a circle, cycloheptane and cyclooctane stencil which should cover most of the organic molecules you might encounter, but the regular Pocket Chemist is also brimming with Physics chemical constants and formulas. It is extremely durable, yet lightweight and even thinner than most plastic credit cards. I carry all four pocket tools with me at the same time, and that doesn't add much to the volume of my wallet. This is literally the perfect gift for any chemistry fanatic. Can't recommend enough!
