- Many envelopes (each one to resistor value);
- Binder wooden box;
Just print the resistor values on the top of envelope, put resistor inside, and put inside the box.
In my case, I used 100 envelopes, spent only R$15,00 (USD$ 6,00) and left space inside the box.
You can use the same ideia to store other kinds of components, such as capacitors, diodes, etc
Thanks to friend Rui to give me that ideia.
