This lot has only been sorted through for  minifigures, and non lego pieces. Sets include star wars, batman, ninja, castles and knights, Lego city, and more. This is based on the minifigures I pulled out of here.

The box weighs 1lbs 9.75oz. The rest of the weight is in lego. Which 21 pounds. I added a bit more than an extra pound to make up for any missed non lego pieces. Pieces are used but clean.
