True North Bricks
“If you are trying to fill out your LEGO city road work crew, this set is a really good buy. You get a very good value per brick, a nice warning sign, and an excellent brick to fig ratio. The only real drawbacks to this set are the lack of build time (which is to be expected... More with a polybag), and a fairly generic Minifigure. A little more printing would have made this fig nicer. I still recommend this set though. It is a cheap way to get a nice sign, and a road worker.”

“30357 Road Worker is an example of a perfect polybag in my opinion. Not only does it offer great play value in relation to its size but the vehicle could easily form part of a full construction site display. The addition of some rare parts is also very welcome and I would... More therefore recommend this set, even to those who only want the printed 2x4 tile.”
