@KoiwiGal - That's a good idea, although personally I have a whole bathroom travel kit, so I don't have to worry about that. It's made of plastic and it has special holders for everything, including the toothpaste and brush, as well as special bottles that I can fill with shampoo and conditioner.
Since the case is solid, I don't have to worry about it getting squished in transit, although I suppose enough weight could theoretically crack the case. That hasn't happened so far though.
The only drawback is that it's quite bulky. If you are just going somewhere local and you know that you'll have access to shampoos and things, you might be better off with just a travel toothbrush.
