In another thread I started, I detailed how I built my kit.
In the travel section at Walmart (or elsewhere) get the plastic rectangular soap holders. They hold a lot of Q-tips and cleaning patches perfectly.
Get the travel q-tip plastic case and fold up your silicone cloth and it fits nicely in there (mine did anyway).
The q-tip case is also the perfect size for the foam ear plugs. I put 8 or 10 pair in mine, in case I bring a guest shooting.
The tooth brush holders were a perfect fit for my nylon brushes I picked up at my local indoor range. Two brushes bristes in just fit.
The snap caps and chamber flags are in a AA battery case I picked up online for $1.
Finally the brushes and jags for my cleaning kit are in the ear plug case with the chain.
