Wooden building blocks. Purchased at Toys "R" Us. These are over 10 years old. I bought them because they are not painted, so they are safe for small children. These are blocks that were used as a secondary set. I have forgotten the manufacturer's name. The packaging was a cylindrical box with a picture of a foreign boy playing with blocks. It is also recommended to keep them at your parents' house and enjoy playing with them with Grandma when you visit. Thank you for looking.
