Small parts containers.
Not sure what you guys use to store small parts and to prevent them from going AWOL.
I got 2 cheap and handy containers:
1.) Frisk Gum boxes, simply stick a post-it note to top to say what's in it.
2.) Cosmetic containers, those are small clear round containers that can be screwed on top of each other and the top one can be sealed with a screw-on lid.
I use the second option mostly for small screws, pe and resin bits.
