This is a SLAM DUNK jigsaw puzzle. The pieces are made of wood. The box has some damage and dirt, but the pieces themselves are clean. I assembled it once and confirmed that all the pieces are present. When shipping, I plan to disassemble it completely, but if you prefer, I can ship it partially assembled. (In this case, please let me know in the comments before you buy.) Please read and understand my profile before making a purchase. Thank you.
