Brix Blox 1000 Vintage 1970s Plastic Building Blocks Bricks Set Sears Japan

Vintage late 1970s or early 1980s Lego sized (but not compatible with) plastic building blocks. These are actually Loc Blocs by Entex but were just renamed to sell through Sears. Box is full without the manual, I have not counted to confirm their are 1000 pieces as stated on the box so sold as is.
