Good but not great quality cars, these are about what one expects at the $22/unit price point. They seem like a good option for building up a collection of rolling stock needed for longer consists without breaking the bank. The couplers are body mounted Microtrains style knuckler couplers and are in gauge per NMRA. This set comes in individual pressboard boxes with plastic packing -- no jewel cases. They run nicely, couple and decouple well, and do not look like plastic toys so overall a good choice.
