Recently, I've spent more time on the road than I'm home so I'm basically living out of my carry-on. I'm a bit particular about my toothpaste and would love to bring it along -- naturally, it only comes in 4.2 oz containers. Has anyone encountered a refillable 2 or 3 oz tube?

You ladies solved my perfume dilema so I'm hoping you can do the same for toothpaste!
