Thank you for viewing. This is a LEGO brick parts set. It's a set containing various parts. The case size is approximately 23cm x 32cm (length x width). I don't know the specific names of the small parts, but I'm selling them because my child has grown up and no longer uses them. I will include the clear plastic case, but it has scratches and is offered as a bonus. Please understand that no claims or returns are accepted after purchase.
