I know that that there is another family set with 23 pcs which is being sold to overseas. The quality is better than the Family set (20pcs). In addition, the eductional CDs and lealets are more clear and in high quality. They claimed that the products has passed the safety requirements of the baby toys.

Actually, it is really cheap to buy from mainland China directly. But the quality is not guaranteed. Previously, I have tried to buy some Montessori products via Taobao website. But the quality was not acceptable. I was very disappointed about it.
