4 kg of mixed lego pieces and incomplete old sets. I estimate that 90% of it is genuine lego. My daughter did get a few small compatible sets and these are mixed in. I have made every effort to ensure that there aren't any non lego pieces, so I added a bit extra in case you find a pirate coin or a marble etc. I did go through it by the handful.

The mini figures are not in their original outfits but they are all complete with accessories and are not compatibles.
