Enclosed is 14.9 kg of lego / Lego Technics . There are also some sets included but they are mixed and our son did not keep the boxes so it is sold as a bundle . there are a number of bases included in this package also . We can include the play mat - draw string bag where he kept all the lego making it easier to clean up.Please note this is advertised elsewhere so may be rmoved if sold. this will make a great christmas present. i have split the photos to show the range of parts.
