This is a simple set of building blocks made from beech wood. Although it says 50 pieces, there are a total of 43 pieces because some have been lost or have markings on them. They haven't been used much, so there aren't many scratches, but some have sun discoloration or stains. Thank you for your understanding. I will take them out of the original box and pack them in a Yu-Packet Plus box for shipping. Thank you for looking.
