My lego were purchased from a collector. All parts are original to this set being offered and has been accounted for and verified using brick link. Many parts are very small and can be lost by either buyer or seller, However I have thousands of parts. If any parts of your purchase gets lost, my fault, your fault, anybody's fault they usually can be replaced by me, just send an email using the contact buyer option with the part #. I can only offer this to buyers who have purchased from mets3330 during the last 30 days.
