The tarps come in the same box, so we had to take them out to unfold them and check them out. They looked very well assembled and all the hardware like grommets looked well pressed and no wrinkles, the reinforcing webbing along the sides was sewn tightly and the grommets were all in a perfectly straight line. The 20 mil Fabric is very heavy duty, and all sections looked well assembled. This tarp will last a very long time.
