This is a set of New Blocks. I haven't counted them, but I've filled a cardboard box with parts and blocks. It includes a series that can be used to build the Doctor Yellow train. I've also purchased additional parts (like tires) from the series, so I think you'll enjoy it. I have disinfected them with alcohol, so you can use them right away. Please understand that these were used by a child and will be shipped in an Amazon cardboard box. Thank you.
