Thank you for looking! This LEGO set uses EVA resin, making it soft, safe, and durable. It's the largest size LEGO block. LEGO Soft is a product that is no longer produced or sold, making it very rare. It is not new. My child and I played with it a lot when they were small, so there are some stains and minor scratches. It is not perfectly complete. Also, as shown in the photos, please understand that there is some discoloration due to age and use. Red: 30 pieces Blue: 16 pieces Green: 14 pieces Yellow: 21 pieces Total: 81 pieces Thank you very much. m(__)m
