humangear GoToob+ Travel Tube: Small 53ml Clear

Great travel tool. It's a beautifully designed thing and really handy for travel. The sealing mechanism is a really effective feature and nothing escapes, even with pressurisation of an aeroplane cabin.
The only thing you really must consider, though, is what it is that you're hoping to put in this thing. There are a number of ingredients which cannot be placed in it. Shampoo? Conditioner? Body wash? You're golden! BUT, I was hoping to take some aftershave balm in it and it turns out my balm has alcohol in it, so it's a no-go. Shattered, too, are my dreams of mixing cocktails and storing them in these things for in-flight refreshments (not really- who would want to squeeze out an old fashioned out of a tube?) Anyways, it's a lovely thing, but just do your research into whether that which you're hoping to store in it is compatible with it.
