#3 Stash Jar with thumb-opened secret compartment
This is a stash jar with a secret compartment on the bottom. The bottom lid has divots for your thumb or fingers to twist the cap off. I can change the grippy coils in the middle.
#1 Stash Jar (ugly colors for contrasting the parts)
First mock up of the stash jar with colors so ugly it will make children cry. I can change the colors to whatever you would prefer, I am merely trying to illustrate the parts.
