Pros : Pieces used to look just like the ones in the photo so you got decent sized pieces.
Cons : No choice of colors. Pieces often have scratches in them.
Other Thoughts : You can get a decent mix of colors if you order a pound at one time. You can get around the scatches with your design and construction. Try clear capping to hide the scratches.
In my most recent order I was disappointed to find that many of the pieces were much smaller than pictured, many in a battered state and looking crushed and really beat up. Not sure if this was due to the way they were shipped or just what I got.
