Some are vintage stamped Duplo, some say Lego. Bricks are used and scuffed but still good for play. I wiped down the outside of most of the bricks with alcohol and looked them over but didn't wash the insides or detail clean them. They appear clean but I may have missed something, dust or fingerprints. No complete sets, just a collection of random specialty shaped and printed pieces. See photos. Smoke-free home. Happy to combine shipping.
