There are a ton of ways to reuse empty lip balm containers, and one of them involves making nifty erasers out of eraser clay. HelloMaphie’s video shows you how to make any color eraser you want following a few simple techniques, allowing you to make enough erasers to last the school year in less than an hour. The only things you need from your local craft store are an eraser clay kit and the glue required to put the clay into the lip balm container. Aside from those, you can replace the crafting knife shown in the tutorial with an ordinary knife or even a flathead screwdriver.

This project really is that easy once you get started. Most of the time you spend on this project involves waiting for various things to finish curing on its own, so meanwhile, you can work on other back-to-school crafts!
