Again, Meng high quality. A few 'beat on' concrete Jersey Barriers, three cones and some bases to look like its a stack, two of the plastic water filled barriers, and - of all things- a two piece mold to make your own Jersey barriers. If I had a criticism it is that just one mold means constant mixing, where if you had more you could mix up a larger batch of plaster or whatever, and pour them all at once. The mixture of two different barrier types means you really have to buy more sets to make anything big, Unless you do a lot of casting), and three cones is just too few. I wish you could just buy the individual items in a single box, but it's not too painful, and for everyone you get you get an additional mold, so that's good.
