The description states that these bins are plastic so it's deceiving to me as I was expecting to receive hard plastic bins.  I was shocked when I received them as I quickly found out that they are actually made out of a waxy corrugated heavy-duty cardboard and had to essentially unflatten them to put them together.  Some of the edges of the cardboard were bent and busted apart.  The are 3 bins and were super easy to unfold and make into a recycling bin and once I put the caps on the holes in the top of the bins it didn't affect the strength or durability of the bins at all and none of the flaws showed.  It's very lightweight and easy to move around so you can use as one unit with 3 bins or you can use each bin separately.  I was pleasantly surprised this those so would definitely recommend them.
