These are offcuts of German beech lumber. The size is approximately 460mm long x 25mm thick x 120mm wide. There may be some slight variations due to the nature of the material. Limited time offer: 5kg bag, including shipping, for ¥1000!! German beech is a high-quality material also used for building blocks and tableware, so why not consider it for toy making or handicrafts? These are cut from lumber. There may be knots like those in the photos. Thank you for your understanding. ******* Shipping is included, and will be via courier (Kuroneko Yamato or Sagawa Express). We are sorry, but we cannot ship to Okinawa, Hokkaido, or other remote islands. Please be aware of this. Thank you for viewing. We look forward to your consideration.
