Living in Japan was expensive, and I made few major purchases during the year I spent there. I had a pretty cool Muji bicycle that I really wanted to bring back to the 'States with me, but I couldn't see it making a transpacific journey unscathed, and I sold it before my return, sadly.
I wish I'd had an AeroTech Evolution bicycle case back then. It's designed to protect your (dismantled) bicycle in the cargo hold of an airplane with its vacuum-formed ABS shell, combined with velcro straps and strategically-placed foam tubing. Even better, it's got a lifetime warranty that's valid all over the world.
