Fieldwork Ruler Sticker

You would not believe the effort put into this to make it an accurate ruler! I'm pretty proud of it personally. The sticker is 6" long with inches labeled. No longer use a rock hammer for scale, use an actual scale! I've also included several other helpful hints for fieldwork, including a grain roundness figure. Stick this on your field book and you're good to go! 

These stickers are 6.2" x 1.2" (the ruler itself is 6" x 1"), and are waterproof and scratch and UV resistant. Perfect for field books, water bottles, lunch boxes, and more!
