I use La Toja shavesticks. Nice sized plastic tube with drain holes at the bottom.
What I did was purchase a small push up deodorant stick that is roughly an ounce at the travel section of Target. After the deodorant is exhausted I clean it out and then twist the plunger back to its original position and take some milled shave soap press int in place and let it set overnight.
Works great.
Going to Europe???? Why bring any of your stuff? Just buy it there.
