Pythagoras Blocks and several other items. There is damage, signs of use, scribbles, tape residue, etc. Please check the condition in the photos. I have wiped them lightly, but I think it's better to wipe them again before use. The number of blocks varies. These are being sold as junk items. Recycled materials will be used for the packaging cardboard box, bubble wrap, and paper cushioning. Thank you for looking.
