Yank the front out of a Bic Round Stic.
Then the ink tube can be pushed out through the plastic tip from behind.
Fill the tube with snuff (I used a piece of paper as a funnel).
Reinsert the tip.
Remove the cotton from the end of a q-tip and stuff it down into the end of the cap.
This prevents snuff from leaking out from the vents on the cap.
Now you are ready to carry all your favorite snuffs wherever you go.
What are you using to MacGuyver your way to the next whiff?
