Chemistry Ruler Stencil

As a chemist, it's one of the most handiest and coolest gadget I've come across! Just absolutely wonderful!!!

Wallet sized chemistry stencil.

I have to be honest, I am using this gadget for crafting. I make micro models and it is the perfect tool for quick measuring and making cutting small items a dream. The spead this arrived to the UK was super quick, I loved the friendly customer service and updates. And the product is well made, no sharp edges, and definatly an asset to have in your wallet just for the mini ruler!! (Try and find another metal 0.5 mm thin, credit card sized ruler online). Anyway, I recommend this product, and for the price, what have you got to lose...

It's a really interesting thing.

As a student living in a dorm, I hate to keep a lot of things, but I love this item because it's only the size of a card! Art templates are usually made of plastic, so they break easily, but this The Pocket Chemist is strong because because it is made of iron, so there is no need to break it. I first got to know tihis on Instagram, and I bought it because I thiought it might help me. Currently, I often use it my homework.
