I underestimated the size of the largest pot (my fault).  The nice thing about these pots is you can use them inside or outside.  I also thought there was a drainage area in the bottom.  There is a hole in the bottom of each pot so you could put a saucer or something under it.  But it also came with plugs if you want to seal off the hole.  Also, these are very light weight which is especially important for the largest size when it's full of dirt and plants!
