Heavy duty plastic packing crate (Whitemans Green RH17)
It's yellow, and I've had it for years, storing stuff in sheds or garages, but I don't really need it now. It has internal dimensions that are: 38cm wide by 60cm long and 33cm tall. It's a bit scruffy, to be honest, but it is incredibly sturdy!
