These are building blocks I used until about 10 years ago. I enjoyed playing with them a lot, so there are scratches, discoloration, and small marks. I washed them with kitchen bleach, but there may be some unnoticed dirt. Please forgive me if there is any. The manufacturer is unknown. No individual sales or price reductions. They will be sent without individual packaging, in a reused cardboard box (approximately 58cm size). Thank you for your understanding. Please consider purchasing.
