I have some NECA Mini Statues and a couple vehicles from the 200x line available. All are sealed. If I remember correctly only the clam shell on Snout Spout has yellowed but contents are mint.
Vehicle boxes are in good condition be can send pictures if there is a defect/tear/dent in box before sending to confirm sale. Prices include shipping within the US only.
